Senior Labour backbencher Bruce George is to stand down at the forthcoming general election.  Bruce George has been MP for Walsall South since 1974 and from 1997 to 2005 he was the chairman of the cross-party Commons Defence Select Committee.
Bruce George said he had decided "with an extremely heavy heart" to stand down after 36 years for health and family reasons.  Bruce George, has a majority of 7,946.

From his own website:

During his time in Parliament he has specialised in Defence having been chosen to serve on the House of Commons Defence Committee when it was set up in 1979. Bruce went on to Chair the committee between 1997-2005. He has been a member of the Parliamentary Assembly of the Organisation for Security and Cooperation in Europe since 1992 and has served in virtually all of its elected offices including President (July 2002-July 2004) and President Emeritus (July 2004-06). He has also been a member of the NATO Parliamentary Assembly since 1982 and was recently elected as Vice President of the Assembly.

That is well over 120 MP's that are standing down at this election, with the bulk of them being Labour, what does that really tell us about the state of the Labour Party?
