David Cameron has sent an email message to Conservative supporters to reassure them over the terms of his deal with the Liberal Democrats.

The Conservative leader became Prime Minister last night after agreeing a coalition with the Nick Clegg's Liberal Democrats and moved to allay fears his party had compromised on key issues.

He wrote: "Of course, we must recognise that all coalitions are about compromise. This one is no different.

"And I want to take this opportunity to reassure about what was agreed.

"The agreement commits the next Government to a significantly accelerated reduction in the budget deficit, to cut £6 billion of government waste this financial year and to stop the jobs tax.

"The agreement also allows us to carry out key elements of the reform agenda we outlined in our manifesto - an agenda vital to turning our country round - including welfare and school reform.

" Moreover, we have protected our nuclear deterrent. And there will be no amnesty for illegal immigrants, nor the handover of any additional powers to the EU.

"Of course, the agreement also reflects the key priorities and objectives of the Liberal Democrats. This includes fairer funding in education, a fairer tax system and political reform - including a referendum on changing the voting system to the alternative vote.

"But the past few days have not just been about compromise. What was clear as talks progressed is the common ground between the Conservatives and Liberal Democrats. And that is displayed in this agreement, with our commitment to building a green economy, decentralising power and protecting civil liberties - including scrapping ID cards.

"We campaigned on the belief that we're all in this together - and can only solve our problems together to build a stronger, more responsible society. I am confident that the coming together of two political parties to form one strong Government marks a new era for Britain and for British politics.

"Now, let's get down to work."
