LABOUR MP David Hinchliffe is to retire at the next election.
He has represented the Wakefield constituency - which includes Kirkburton and Denby Dale - since 1987 and chairs the Commons health select committee.
Mr Hinchliffe, 54, said he made his announcement now so the party can pick a replacement in plenty of time.
He added: "At the end of this Parliament, I shall have served almost two decades as an MP.
"I was first elected a councillor at the age of 22 and have been either a councillor or an MP for most of my adult life.
"My decision to stand down has been taken for the sole reason that I want to spend more time on other aspects of life outside politics, along with my wife, Julia, and my family."
Mr Hinchliffe said he was very proud of many of the achievements of the Government.
"I am especially proud of the significant increase in resources for the NHS and the biggest hospital building programme in its history," he said.
Mr Hinchliffe said he was certain that the Government would win a third term.
But to win well, its policies had to be underpinned by a return to Labour's basic values.
Mr Hinchliffe added: "I am deeply disturbed by the encouragement of an increased role for the private market in health. The private sector is a major cause of many problems in the NHS."
Tributes were paid to the MP today.
Constituency party chairman Mike Greetham said: "His views, especially on health matters, which were often at odds with the Government, reflect the views of the Wakefield party. We are very proud of him for expressing them so forcefully."
