Cameron and Clegg to renew pledges

David Cameron and Nick Clegg are to reaffirm their commitment to tackling Britain's record deficit and rebuilding the shattered economy in the face of continuing turmoil in Europe.

Amid heightened tensions within the coalition following last week's drubbing in the local elections, the Prime Minister and Deputy Prime Minister will declare their determination to work together and do "whatever needs doing to succeed".

The so-called renewal of their "marriage vows" marks the start of a crucial week for the Government, with the announcement in the Queen's Speech of the legislative programme for the new parliamentary session.

That will be followed by the appearance at the Leveson Inquiry on Thursday of former No 10 communications chief Andy Coulson, followed on Friday by ex-News International chief executive Rebekah Brooks, which once again threatens to throw an unwelcome spotlight on the Tories' relations with Rupert Murdoch.

Meanwhile, recriminations within the coalition spilled over with Liberal Democrat deputy leader Simon Hughes accusing Tory MPs of behaving as if they were "born to rule".

Some Conservative MPs, meanwhile, have been setting out their agenda for an "alternative Queen's Speech" - including traditionalist Tory demands for a referendum on repatriating powers from Brussels and an expansion of grammar schools.

In contrast to their initial appearance together two years ago in the Downing Street rose garden, Mr Cameron and Mr Clegg will set out their renewed commitment to work together against the more prosaic backdrop of a factory in Essex.

The tone too will be altogether more sombre, with the Prime Minister warning that the damage done in the financial crash of 2008 was "greater than anyone thought", while Mr Clegg will liken it to a "giant heart attack".

Mr Cameron will stress that their "number-one priority" was still to keep Britain safe from the financial storm raging in the eurozone and to rescue the economy from the "mess" left by the last Labour government.

In his remarks, Mr Clegg will dismiss claims the coalition has an "ideological obsession" with shrinking the size of the state, arguing there was a "clear moral responsibility" to deal with the deficit and not leave it to future generations.
