The Conservative Government will deliver its manifesto "in full", a beaming David Cameron told his party's MPs and peers as he proudly held up the party document at a meeting of their 1922 Committee.

The committee corridor was packed with journalists, waiting outside the Gladstone Room, as the triumphant Tories filed in to hear their leader thank them for their hard work and to set out his programme for government.

On the way in, the Prime Minister chatted to reporters, joking that the Labour leadership contest was going to be "lovely to watch".

He admitted to nerves on election day even though his aides had assured him the exit poll, which put the Conservatives as the largest party, was "definitely right" but admitted it was the key Nuneaton result - a target Labour seat - which had convinced him the election was swinging his way.

He said the Rochester result, which Tory-turned-Ukip MP Mark Reckless lost, was a highlight of the night, and stressed how he was "very sad" about the loss of former Minister Esther McVey in Wirral West.

He promised a "ministry of all the talents" as he continued to assemble his new Government; speculation is rife that David Mundell as the only Scottish Conservative MP will be appointed Scottish Secretary.

Mr Cameron expressed sadness at how Scottish Tory John Lamont had just missed out on winning the Berwickshire, Roxburgh and Selkirk seat by 328 votes to the SNP, suggesting it was the Liberal Democrats that cost the Conservatives the seat and from having two Scottish MPs.

As he entered the Gladstone Room, there was a tumultuous reception from his MPs. During the 42-minute meeting, the roar of banging desks could be heard repeatedly as MPs signalled their approval of the PM's message. He highlighted three topics - making the Tories the party of working people, making it the party of compassion, particularly in light of the welfare reforms to come, and of the United Kingdom, bring all of its parts together.

One early departure from the Conservative love-in was that of Sir Nicholas Soames, the former Defence Minister, who said: "It's hot in there. I'm off for a cocktail."

At the end, unusually, the desk banging turned into rapturous applause.

As he emerged after putting his jacket back on, Mr Cameron quipped: "Well, I think that went okay."

Then, Chancellor George Osborne disappeared into a gaggle of reporters, describing the event as a "moment of real personal celebration for David Cameron's leadership".

He said: "I've never seen anything quite like it in all the years I've been turning up to those meetings. Some individual heroes of the campaign were singled out like the new MPs for Twickenham(Vince Cable's old seat), Morley (Ed Balls's old seat) and Thanet South (the seat Nigel Farage was fighting) and Rochester (the seat the Tories regained from Ukip) and indeed all the people who fought tight marginal battles.

"The big message was that there is an opportunity for the Conservative Party to be the party of working people in this country, the party of aspiration; that space is available for us. The manifesto commits us to that and we're going to deliver the manifesto in full. David Cameron held the manifesto up and said this is what we were elected on, this is what we will deliver and we need to get on and do it."

The committee corridor was filled with smiling Tory faces. There were hugs and kisses as some MPs had only met their colleagues for the first time since the dramatic election night

To help, the new MPs all wore a green sticker on their clothes to mark them out as rookies.
