Doctors have told the prime minister to take a day off to rest at home

This morning the PM was feeling under the weather.

He went to Stoke Mandeville Hospital where they advised him to go to the Hammersmith.

There it was established that he had an irregular heartbeat. A cardio-version was administered to regulate it.

This was completely successful. He was in hospital for four to five hours and he's now back in No 10.

The hospital says this is a relatively common condition and is easily treated. He has suffered no damage and is fine.

There is no reason why this should re-occur. They have advised him to rest for 24 hours.

Jack Straw will therefore do the European Council statement tomorrow.

The prime minister will however hold meetings during the day and will be back fulltime at his desk on Tuesday morning.
