Tony Blair will be back at "full throttle" today following his heart scare, the Prime Minster's official spokesman said last night.

Foreign Secretary Jack Straw stood in for Mr Blair to deliver a statement to MPs yesterday. But Mr Blair held a string of meetings inside Downing Street despite being told to "take it easy" after Sunday's drama.

And Mr Straw told MPs: "I am pleased to tell the House that he is in very good form and fully recovered."

The Prime Minister will press ahead with his full diary for the rest of the week including his monthly televised media briefing.

Number 10 released details of the PM's day as they sought to stress there was no lasting impact on his health and Premiership.

However, the scare inevitably provoked speculation that it could persuade Mr Blair to step down earlier than he might have.

The Prime Minister spent five hours in hospital after complaining of chest pains while staying at Chequers, his official country home in Buckinghamshire. Doctors at London's Hammersmith Hospital gave him a cardioversion, an electric shock, to correct an irregular heartbeat.

Yesterday morning, Mr Blair was "fit, fine, in good spirits and 100 per cent recovered", said his spokesman.

At 9am Mr Blair chaired Downing Street's daily strategy meeting and then spoke to Irish Taoiseach Bertie Ahern about the Northern Ireland peace process.

He later had further meetings, including discussions with Deputy Prime Minister John Prescott.

Mr Blair will attend his regular audience with the Queen today before delivering a speech on public services and facing Prime Minster's Questions tomorrow.

On Thursday, he will go ahead with his monthly televised media briefing after chairing Cabinet and before setting off on a regional tour.

"Clearly, the Prime Minister would take medical advice but this is not a long-term medical condition," his spokesman added. "It is relatively minor."
