George Mudie MP, who represents Leeds East for the Labour Party, has said he would vote for independence if he still lived in Scotland.
The MP, who was born in Dundee and went to Waid Academy in Anstruther, told BBC Radio Leeds: “If I were in Scotland I would be voting for an independent Scotland.”
Mudie has been an MP since 1992 and is set to stand down in 2015.
His political career began when he was elected to Leeds City Council in 1971, eventually becoming the leader of the administration in 1980.
He was parliamentary under-secretary at the Department for Education and Employment in Tony Blair’s first government, and has been described as a “fantastic MP” by Labour leader Ed Miliband.
He has also, since 2001, been a member of the Treasury Select Committee, which examines the administration and policy of the Treasury and its associated bodies, including the Bank of England.
A spokesperson for Scottish Labour said Mudie was “entitled to his opinion”.
Former Scottish Labour chairman Bob Thomson, who is now part of Labour for Independence, commented: “Many Labour voters and members are realising that an independent Scottish Parliament is the only way of ensuring that the enormous wealth of Scotland works for all the people of Scotland.”
Scotland’s independence referendum takes place on 18 September.
