Prime Minister Gordon Brown has repeatedly ruled out a referendum on the EU treaty, despite calls from the Conservatives, trade unionists and a growing number of his own MPs.
Mr Brown argues a referendum is not needed as the treaty is very different to the failed EU constitution, on which a referendum had been promised in Labour's 2005 manifesto.
'Real choice'
Sir Menzies says he agrees with the prime minister - but as an ardent pro-European he is "not prepared to allow David Cameron to lead the Europhobes and their allies in sections of the media, to distort the debate on Europe without challenge".
The Lib Dem leader, who was expected to face calls to back a treaty vote from some of his own MPs at his party's conference, said voters should be given a "real choice".
"If there is to be a referendum it shouldn't be restricted to a comparatively minor treaty. It must be a decision about the EU as a whole.
"Let's have an honest debate on the European Union followed by a real choice for the British people. That means a referendum on Britain's membership of the EU.
"We would ask the British people the big question - whether to remain in the European Union or not.
"I will lead the Liberal Democrats at the forefront of that debate. "We will make the overwhelming case for Europe and trust the people to make the right choice."
Politcal union
Voters backed the UK's continued membership of the European Economic Community (EEC) in 1975 by a large majority, in the country's first nationwide referendum.
Since then, what was originally an economic agreement has been transformed into a political union through a series of treaties.
Critics, including the UK Independence Party (UKIP), have long argued that the public should be given another say over Britain's continued membership.
But Sir Menzies' intervention is the first time one of the main pro-European parties in Britain has added its voice to such calls.
