Sheffield MP Meg Munn has revealed she will not stand for reselection at the 2015 General Election.
After 14 years serving as Labour’s MP for Sheffield Heeley, she has announced she believes the time has come to take her energy and experience on to new challenges.
Ms Munn said: “It has not been as easy decision to make.
“However, I am confident it is the right one – for me, the party and the constituency.
“It has been a great privilege to represent the constituency since 2001 and I will look back with pride on my time in Parliament.
“When I first joined the Labour Party in Heeley, nearly 40 years ago, I never dreamt I would one day become its Member of Parliament.”
Following Ms Munn’s election in 2001, she held various ministerial positions.
From 2005 to 2007 she was the minister for women and equality and introduced civil partnerships in December 2005, was responsible for the Equalities Act 2006 and was involved in the Work and Families Act 2006.
In 2007, she became Parliamentary Under Secretary of State for Foreign Affairs.
She was also chairman of the Westminster Foundation for Democracy, established to promote democracy mainly in Eastern Europe, the Middle East and Africa.
However, she said her happiest memories are of times spent in her own constituency – visiting schools, community groups and projects.
She said: “I’ve enjoyed talking to people who are trying to make things better for others and hope I’ve helped.
“I look back with satisfaction on achievements I was centrally involved in, such as achieving change to gender-neutral language in our legislation, allowing unmarried couples in stable relationships to adopt, introducing civil partnerships and helping a great number of constituents with problems great and small.”
