EU referendum: 100 Tory MPs back call for vote

A Conservative MP says almost 100 colleagues have signed a letter calling on David Cameron to prepare legislation committing the UK to an EU referendum after the next election.

John Baron's letter does not specify an in-or-out referendum.

The wording would be decided later but "should relate to the nature of our... relationship with the EU", he said.

He says the law would "address the lack of public trust" which meant promises to hold such a vote "hold little sway".

Current laws commit the government to hold a referendum if Britain is asked to cede powers to Brussels.
