Cable is to quit as Lib Dem leader in May
Sir Vince Cable will step down as leader of the Liberal Democrats in May.
The former Business Secretary said he wanted to make way for the "next generation" of politicians to lead the party.
In an interview timed to coincide with Liberal Democrats' spring conference in York, which begins tomorrow, Mr Cable told The Daily Mail he would continue working as a backbench MP after stepping down.
In a statement, the 75-year-old veteran politician said: "I indicated last year that once the Brexit story had moved on, and we had fought this year's crucial local elections in 9,000 seats across England, it would be time for me to make way for a new generation.
"I set considerable store by having an orderly, business-like succession unlike the power struggles in the other parties.
"So I wanted you, our members, to know that, assuming Parliament does not collapse into an early general election, I will ask the party to begin a leadership contest in May."
He added: "It has been my great privilege to lead the Liberal Democrats at this crucial time."
