The Glasgow East constituency was created for the
2005 general election. Its area came from the majority of the
Glasgow Baillieston constituency, with the remainder formed from the
Glasgow Shettleston constituency. It is one of the most deprived constituencies in the UK, with 30% of the working-age population on unemployment or incapacity benefit and nearly 40% of children growing up in homes where there is no adult in paid employment. At the 2005 general election, the new Glasgow East seat was
Labour's 26th
safest seat in terms of percentage majority, and within Scotland, the seat at which it received its second-highest share of the vote. At the 2005 general election, Labour defeated the
Scottish National Party by a majority of 13,507 votes, who beat the
Liberal Democrats to third place by 1,603 votes. Prior to his 2005 win at Glasgow East, Marshall had continually held the predecessor seat of
Glasgow Shettleston since
1979. Shettleston had been held continuously by previous Labour Party members since an
Independent Labour Party member defected to Labour in 1947. The
Glasgow Baillieston constituency, and its predecessor seat
Glasgow Provan, had always returned Labour MPs since its creation in 1955. At the
2007 Scottish parliamentary election, Labour lost power to the SNP, who formed a
minority government. At this election, the SNP Deputy First Minister
Nicola Sturgeon won the neighbouring
Glasgow Govan Scottish Parliament constituency with a swing from Labour of 10.7%, while all other Glasgow constituencies remained in Labour control. On 28 June 2008, Marshall informed local party leaders that he would be stepping down on medical advice, after 10 weeks of
sick leave from the House of Commons. a device allowing him in effect to
resign as an MP, triggering the by-election ==Political situation==
