PRESS ASSOCIATION -- UK Independence Party leader Nigel Farage will accuse David Cameron of "mass deception" of Conservative voters over issues like immigration, human rights legislation and a referendum on the EU.
In a clear bid for votes on the eurosceptic wing of the Conservative Party, Mr Farage will use a speech to the Ukip annual conference in Eastbourne to accuse the Tories of making pre-election promises on Europe which they had no intention of keeping.
The speech comes amid unrest on the Tory backbenches over Europe, with a group of young MPs due to meet on Monday to discuss how to recast Britain's relations with the EU and veteran eurosceptic Bill Cash tabling a Bill demanding a referendum on any moves to closer fiscal union.
Meanwhile, former Conservative MP Neil Hamilton - a Ukip member for about a year - will seek a move to the party's frontline by standing for a post on its ruling national executive committee.
In a full-scale attack on Conservative credentials on the European Union, Mr Farage will tell the conference that there has been a "total breakdown in trust" in all the major parties, with Labour voters disillusioned by the financial crisis and Iraq and Lib Dems by the U-turn on tuition fees.
"But those who must be feeling the most let down, the most disappointed, are the millions of Conservative voters who believed the promises of David Cameron," he will say.
"They have begun to realise that when Mr Cameron makes promises about EU referendums, immigration figures or human rights legislation, that he is doing so simply to get their vote without ever meaning it himself. The Tories' election strategy is one of mass deception and if you're a patriotic, anti-EU Tory voter then your party has disappeared."
Mr Farage will also use his speech to float a proposal for an English Parliament, to resolve the tensions caused by devolution of some powers to Scotland, Wales and Northern Ireland.
A day after the Government announced the creation of a commission to investigate the so-called West Lothian question, the Ukip leader will say that his party is the first to draw up serious proposals to answer calls for "English votes for English laws".
"What we have in the UK at the moment is a situation where the English people are the ones most likely to break up the Union because they feel used and under-represented," Mr Farage will say.
