North Southwark and Bermondsey MP Simon Hughes has failed in his bid to win the leadership of the Liberal Democrats. He remains president of the party.
"This has been a really good leadership election campaign," said Mr Hughes, who went on to pay tribute to Sir Menzies and offer his "complete and unqualified support" to the new leader.
This is the second time that Hughes, who has represented North Southwark and Bermondsey since 1982, has stood unsuccessfully for the party leadership. In 2004 he was elected as the party's federal president. He was also the Lib Dem candidate for the London mayoralty in 2004.
