House of Commons

Having previously contested Southend West in the 1987 General Election, Smith was selected to stand for election for Labour in Basildon nearly a decade later in December 1995 through an all-women shortlist.^[3] She was elected for Basildon at the 1997 general election, replacing the Conservative MP David Amess, who had moved to contest the nearby safer seat of Southend West, which Smith previously fought herself, when Basildon's boundaries were slightly redrawn, aware that his small majority was almost certainly going to be overturned by Labour. She was re-elected comfortably in 2001 and 2005.

In December 1997, Smith introduced the Private Member's Bill to minimise waste generation, and was successful in negotiating its passage through Parliament to become the Waste Minimisation Act 1998.^[4]

Smith was appointed a Government Whip in 2001, before being promoted to Parliamentary Under Secretary of State for Northern Ireland in October 2002. In 2006, she was moved to the Department for Communities and Local Government, with responsibility for Fire Services.

On 28 June 2007, Smith was appointed as a Parliamentary Private Secretary to the new Prime Minister Gordon Brown, entitling her to attend Cabinet. She gave up this role at the reshuffle of June 2009, to enter Government in the Cabinet Office as Minister of State for the Third Sector,^[5] when she was sworn of the Privy Council.^[6]

The old Basildon seat was abolished in the 2010 general election, and she stood for and lost the contest to the new South Basildon and East Thurrock constituency, which predominantly covered much of the area she represented in Parliament, to the Conservative candidate Stephen Metcalfe. Adverse boundary changes contributed to her defeat, as some of her voters were moved into the new Basildon and Billericay seat, whilst the new South Basildon seat took in strong Conservative wards in East Thurrock. Labour would have possibly held the old Basildon seat, and Smith herself said in a 2011 House of Lords debate: “Prior to my election to the other place in 1997, the constituency boundaries in my constituency were redrawn. For the 2010 election, the constituency boundaries were redrawn again, which may explain why I am in your Lordships' House and not in the other place”.^[7]

Expenses

In June 2009 Smith had to repay over £1,000 for wrongly claimed Council Tax expenses and service charges for her second property in Elephant and Castle. A review by Sir Thomas Legg uncovered further monies over-claimed by Baroness Smith making a total of £1,429 which she later returned.^[8]

House of Lords

Smith was created a Life Peer as Baroness Smith of Basildon, of Basildon in the County of Essex, on 7 July 2010,^[9] following the 2010 Dissolution Honours List. She was introduced into the House of Lords the next day.^[10]

In the Lords, Smith was Labour Spokeswoman for Energy and Climate Change from 2010 to 2013, Northern Ireland from 2011 to 2012 and the Home Office from 2012 to 2015. She also served as Opposition Deputy Whip in the House of Lords from 2012 to 2015. On 27 May 2015, Smith was elected unopposed as Labour's Leader in the Lords, and so joined Harriet Harman's Shadow Cabinet.^[11]

In June 2016, Smith and Lords chief whip Lord Bassam of Brighton stated they would boycott shadow cabinet meetings while Jeremy Corbyn remained leader of the Labour Party, but returned to attending shadow cabinet four months later.^[12][13]

In September 2017, she was named at Number 71 in 'The 100 Most Influential People on the Left' by commentator Iain Dale.^[14]
