The Labour Party leadership of Ed Miliband began when Ed Miliband was elected as Leader of the UK Labour Party in September 2010, following the resignation of Gordon Brown after the formation of the Conservative–Liberal Democrat coalition government in the aftermath of the 2010 general election.

Miliband's tenure as Labour leader was characterised by a leftward shift in his party's policies under the "One Nation Labour" branding which replaced the "New Labour" branding, and by opposition to the Conservative–Liberal Democrat coalition government's cuts to the public sector. Miliband also abolished the electoral college system to elect the leader and deputy leader of the Labour Party, and replaced it with a "one member, one vote" system in 2014. He led his party into several elections, including the 2014 European Parliament election.

Miliband appointed his first Shadow Cabinet in October 2010, following the Labour Party Shadow Cabinet elections. These elections were the last such elections before they were abolished in 2011. Miliband conducted two major reshuffles in 2011 and 2013, with a number of minor changes throughout his term. Following David Cameron's success in forming a majority Conservative government at the 2015 general election, Miliband resigned as leader on 8 May 2015. He was succeeded after a leadership election by Jeremy Corbyn.

Following the formation of the Conservative–Liberal Democrat coalition government on 11 May 2010, Gordon Brown resigned as Prime Minister of the United Kingdom and Leader of the Labour Party with immediate effect. Deputy Leader Harriet Harman took over as Acting Leader and became Leader of the Opposition. On 14 May, Ed Miliband announced that he would stand as a candidate in the forthcoming leadership election.^[1] He launched his campaign during a speech given at a Fabian Society conference and was nominated by 62 fellow Labour MPs. The other candidates were left-wing backbencher Diane Abbott, Shadow Education Secretary Ed Balls, Shadow Health Secretary Andy Burnham and Miliband's elder brother, Shadow Foreign Secretary David Miliband.^[2][3]

On 23 May, former Labour leader Neil Kinnock announced that he would endorse Ed Miliband's campaign, saying that he had "the capacity to inspire people" and that he had "strong values and the ability to 'lift' people".^[4] Other senior Labour figures who backed the younger Miliband included Tony Benn and former deputy leaders Roy Hattersley and Margaret Beckett. By 9 June, the deadline for entry into the leadership election, Miliband had been nominated by just over 24% of the Parliamentary Labour Party, double the threshold. By September, Miliband had received the support of six trade unions, including both Unite and UNISON, 151 of 650 Constituency Labour Parties, three affiliated socialist societies, and half of Labour MEPs.^[5]

Ed Miliband subsequently won the election, the result of which was announced on 25 September 2010, after second, third and fourth preferences votes were counted, achieving the support of 50.654% of the electoral college, defeating his brother by 1.3%.^[6] In the fourth and final stage of the redistribution of votes after three candidates had been eliminated, Ed Miliband led in the trade unions and affiliated organisations section of the electoral college (19.93% of the total to David's 13.40%), but in both the MPs and MEPs section (15.52% to 17.81%), and Constituency Labour Party section (15.20% to 18.14%), came second. In the final round, Ed Miliband won with a total of 175,519 votes to David's 147,220 votes.^[7]

On becoming Leader of the Labour Party on 25 September 2010, Miliband also became Leader of the Opposition. At 40, he was the youngest leader of the party ever. At his first Prime Minister's Questions on 13 October 2010, he raised questions about the government's announced removal of a non-means tested child benefit.^[8] In December, he appointed Tom Baldwin as his director of communications.^[9]

During the 2011 military intervention in Libya, Miliband supported UK military action against Muammar Gaddafi.^[10] Miliband spoke at a large "March for the Alternative" rally held in London on 26 March 2011 to protest against cuts to public spending, though he was criticised by some for comparing it to the anti-apartheid and American civil rights movements.^[11][12][13]

A June 2011 poll result from Ipsos MORI put Labour 2 percentage points ahead of the Conservatives, but Miliband's personal rating was low, being rated as less popular than Iain Duncan Smith at a similar stage in his leadership.^[14] The same organisation's polling did find that Miliband's personal ratings in his first full year of leadership were better than David Cameron's during his first full year as Conservative leader in 2006.^[15]

In July 2011, following the revelation that the News of the World had paid private investigators to hack into the phones of Milly Dowler, as well as the families of murder victims and deceased servicemen, Miliband called for News International chief executive Rebekah Brooks to resign, urged David Cameron to establish a public, judge-led inquiry into the scandal, and announced that he would force a Commons vote on whether to block the News International bid for a controlling stake in BSkyB. He also called for the Press Complaints Commission to be abolished – a call later echoed by Cameron and Nick Clegg – and called into question Cameron's judgement in hiring former News of the World editor Andy Coulson to be his director of communications.^[16] Cameron later took the unusual step of saying that the government would back Miliband's motion that the BSkyB bid be dropped, and an hour before Miliband's motion was due to be debated, News International announced that it would withdraw the bid.^[17][18]

Following the riots in England in August 2011, Miliband called for a public inquiry into the events, and insisted society had "to avoid simplistic answers". The call for an inquiry was rejected by David Cameron, prompting Miliband to say he would set up his own. In a BBC Radio 4 interview shortly after the riots, Miliband spoke of an irresponsibility that applied not only to the people involved in the riots, but "wherever we find it in our society. We've seen in the past few years...MPs' expenses, what happened in the banks". Miliband also said Labour did not do enough to tackle moral problems during its 13 years in office.^[19] In December 2011 Miliband appointed Tim Livesey, a former adviser to the Archbishop of Canterbury, to be his full-time chief of staff.^[20]

In his first speech of 2012, Miliband said that if Labour won the 2015 general election times would be difficult economically, but Labour was still the only party capable of delivering "fairness". He also said he would tackle "vested interests", citing energy and rail companies.^[21] Following the announcement in late January 2012 that the chief executive officer of the nationalised Royal Bank of Scotland, Stephen Hester, would receive a bonus worth £950,000, Miliband called the amount "disgraceful", and urged David Cameron to act to prevent the bonus. Cameron refused, saying it was a matter for the RBS board, leading Miliband to announce that Labour would force a Commons vote on whether or not the government should block it. Hester announced that he would forego his bonus, and Miliband said Labour would carry on with a Commons vote regardless, focusing instead on the bonuses of other RBS executives.^[22][23] Following George Galloway's unexpected win in the March by-election in Bradford West, Miliband announced he would lead an inquiry into the result, saying that it "could not be dismissed as a one-off".^[24]

In April 2012, in the midst of a debate about the nature of political party funding, Miliband called on Cameron to institute a £5,000 cap on donations from individuals and organisations to political parties, after it had been suggested that the government favoured a cap of £50,000.^[25] On 14 July 2012, Miliband became the first Leader of the Labour Party to attend and address the Durham Miners' Gala in 23 years.^[26] In the same month, Miliband became the first British politician to be invited to France to meet the new French President, François Hollande.^[27]

On 23 January 2013, Miliband stated that he was against holding a referendum on the UK's membership of the European Union because of the economic uncertainty that it would create.^[28] On 18 March 2013, Miliband reached a deal with both Cameron and Clegg on new press regulation laws following the Leveson Inquiry, which he said "satisfied the demands of protection for victims and freedom of the press".^[29] In August 2013, following the recall of parliament to discuss an alleged chemical attack in Syria, Miliband announced that Labour would oppose any military intervention on the basis that there was insufficient evidence.^[30] David Cameron had been in favour of such action but lost the ensuing vote, making it the first time that a British prime minister had been prevented from instigating military action by parliament since 1956.^[30]

At the Labour conference in September 2013, Miliband highlighted his party's stance on the NHS and announced if elected Labour would abolish the bedroom tax. The conference included several 'signature' policies, such as strengthening the minimum wage, freezing business rates, building 200,000 houses a year, lowering the voting age to 16, and the provision of childcare by primary schools between 8 am and 6 pm. The policy that attracted the most attention was the commitment to help tackle the 'cost-of-living crisis' by freezing gas and electricity prices until 2017 to give time to 'reset the market' in favour of consumers.^[31] In January 2014, Miliband extended the concept of reform to include the 'big five' banks, in addition to the 'big six' utility companies, and discussed the impact of the cost-of-living on the 'squeezed middle', saying "the current cost-of-living crisis is not just about people on tax credits, zero-hour contracts and the minimum wage. It is about the millions of middle-class families who never dreamt that life would be such a struggle".^[32]

Throughout 2014, Miliband changed Labour's policy on immigration, partly in response to UKIP's performance in the European and local elections in May, and the close result in the Heywood and Middleton by-election in October. Miliband committed to increase funding for border checks, tackle exploitation and the undercutting of wages, require employers who recruit abroad to create apprenticeships, and ensure workers in public-facing roles have minimum standards of English. In November 2014, Labour announced plans to require new EU migrants wait two years before claiming benefits.^[33][34]

Miliband campaigned in the Scottish independence referendum with the cross-party Better Together campaign, supporting Scotland's membership of the United Kingdom. Opinion polls showed solid leads for the 'no' campaign, with a 20 point-lead on 19 August. However, by the end of the month, the lead had fallen to just 6 points, with YouGov analysis showing a big shift in support among Labour supporters. Miliband made an unplanned visit to Lanarkshire to draw a contrast between a Labour and Conservative future for Scotland within the UK.^[35] A poll on 7 September showed a 2-point lead for the 'yes' campaign, leading to a joint commitment by Miliband, Cameron and Clegg for greater devolution to Scotland through a version of home rule.^[36] The results on 19 September showed victory for the 'no' campaign, 55.3% to 44.7%.^[37]

The day after the referendum, Cameron raised the issue of 'English votes for English laws', with Miliband criticising the move as a simplistic solution to a complex problem, eventually coming out in favour for a constitutional convention to be held after the general election.^[38][39]

The Labour party conference in Manchester on 21–24 September occurred days after the Scottish referendum result. Miliband's conference speech was criticised, particularly after he failed to deliver sections on the deficit and immigration, after attempting to deliver the speech without notes.^[40] At the conference, Miliband pledged to focus on six national goals for Britain until 2025, including boosting pay, apprenticeships and housing; a mansion tax and levy on tobacco companies to fund £2.5 billion a year 'time to care' fund for the NHS; a commitment to raise the minimum wage to £8 or more by 2020; and a promise to lower the voting age to 16 ready for elections in 2016.^[41][42]

In February 2015, Labour pledged to reverse the privatisation of the railways by getting rid of the franchising system, after previously saying that they would allow the public sector to bid for franchises.^[43]
