A law professor is calling for Nick Clegg to be prosecuted for fraud over the controversial tuition fee hike.
Ian Grigg-Spall said the Deputy Prime Minister and Liberal Democrat leader should face police action for publicly pledging before the election to oppose a rise while his party was allegedly secretly drawing up plans to abandon the promise.
Mr Grigg-Spall, a professor of law and member of the National Critical Lawyers Group, said he lodged a complaint at a Sheffield police station under Section 2 of the Fraud Act.
"Under the act you have to show dishonesty," he said.
"It seems absolutely clear to me that dishonesty is actually proven by the details in the Guardian story."
An article published in the Guardian last month claimed the Liberal Democrats drew up plans two months before the general election to abandon a pledge to scrap them as part of any coalition deal.
A confidential document drawn up in March by a senior team planning for possible negotiations concluded that insisting on the move - which was opposed by the Tories and Labour - would be a "headache".
The revelations were detailed in a new book about the formation of the Tory-Lib Dem administration by Conservative MP Rob Wilson, extracts of which were published by the Guardian.
The Lib Dems said the document was a recognition of the reality of negotiating with two parties that were diametrically opposed to the policy to scrap any rise in fees.
Mr Grigg-Spall said he had spoken to several law experts who agreed he had a good case.
