However, in 2014, Hosie and most of his SNP colleagues missed a vote on repealing the bedroom tax – the most controversial aspect of the legislation – despite the SNP making opposition to the policy a central part of its campaign for a yes vote in that year's independence referendum. Labour said: “Far from standing up for Scotland, the SNP have stayed at home and let Scotland down.”^[10]

In May 2016, Hosie and Robison announced that they had separated.^[26] This was followed by reports that Hosie and his colleague Angus Macneil had both had an affair with Westminster-based freelance journalist Serena Cowdy.^[27] On 22 May 2016, Hosie announced his intention not to stand for re-election as Deputy Leader, due to "intense scrutiny" by the media of his private life, meaning that his term of office would end at the SNP's annual conference later in the year.^[28]
