Lib Dem MP Quits Parliament Liberal Democrat MP Sarah Teather has announced she will quit Parliament at the next general election. The former minister, who became the youngest MP when she secured a stunning by-election victory over Labour in Brent East almost a decade ago, said her relationship with the party was broken. Explaining her decision to step down in 2015, Ms Teather pointed to the junior coalition partner's decision to back the Conservatives' planned cap on welfare. She told The Observer newspaper: "It was the moment of realising that my own party was just as afraid of public opinion as the Labour Party. Something did break for me that was never, ever repaired. Ms Teather said she was "utterly desolate" when Lib Dem leader and Deputy Prime Minister Nick Clegg, said some immigrants should be asked to pay a £1,000 returnable "bond" when requesting a visa. She said: "It took me some time before I began to communicate with Nick Clegg. I couldn't even be angry. I was utterly desolate. A Lib Dem spokesman said the party was "disappointed" by her decision just a week before the annual party conference and defended its "proud record" in the coalition Government. The spokesman said: "Of course we are disappointed by Sarah's decision. The Liberal Democrats have a proud record in Government, including cutting taxes for working people by £700 and lifting the poorest paid out of tax altogether, helping businesses create a million jobs; investing billions more in schools to help the poorest children and introducing radical plans for shared parental leave. Sarah was a part of this when she served as a minister in the Coalition, as well as playing a key role in ending Labour's disgraceful policy of locking up children for immigration purposes. Ms Teather, who lost her place as an education minister in a reshuffle a year ago, said the latter policy was her "proudest moment in government." In 2003 she rode a wave of anti-Iraq war sentiment to overturn a Labour majority of more than 13,000 and as a rising star of the party managed to increase her majority at the 2005 general election. Following boundary changes she won the Brent Central seat in 2010, by a slim margin of 1,345. She joined the government ranks immediately after the formation of the coalition, as Minister of State for Children and Families but lost her place to make room for the returning David Laws.
