Labour MP for Nottingham North Graham Allen has confirmed he is stepping down as MP after 30 years citing ill health.
The 64-year-old has recently suffered extended periods of ill health and did not feel he could serve for another five years.
He said it was the ‘hardest decision of my life’.
Mr Allen received a number of messages of support on social media site Twitter.
Graham was born in Aspley, Nottingham on January 11 1953, into a mining family with deep roots in the city.
His grandfather was a founder member of Nottingham Labour party.
Mr Allen has served as a senior whip and earlier this decade chaired a select committee on political and constitutional reform.
He has held the seat in his constituency since 1987 after winning it from the Conservatives and has successfully defended it in six further general elections.
