A London MP elected less than two weeks ago today launched a bid to lead his party.
Sir Vince Cable, captured Twickenham for the Liberal Democrats after losing the seat to the Tories in 2015.
The 74-year-old former Business Secretary in the 2010-2015 Coalition government said he was offering 'energy, dedication and drive as well as experience.'
Sir Vince was briefly Acting Leader of the Lib Dems in 2007 following the resignation of 66-year-old Sir Menzies Campbell who stepped down after coming under pressure because of his age.
Sir Vince said he would campaign for a second referendum on British membership of the EU.
Earlier this month Sir Vince indicated he had no interest in replacing Tim Farron.
