Former Italian Prime Minister Silvio Berlusconi has been taken ill during a speech to supporters in northern Italy.

Mr Berlusconi, 70, slumped at the podium at a rally in Tuscany and collapsed into the arms of his aides.

He was examined by a doctor, and a spokesman later said Mr Berlusconi had struggled with the heat and suffered a drop in blood pressure.

Twice prime minister, Mr Berlusconi has been leader of the opposition since losing power in elections in April.

Mr Berlusconi - Italy's richest man - went on trial last week for alleged fraud and money laundering and could face up to 12 years in jail if convicted. He denies all charges against him.

The trial is due to resume in Milan on Monday.

Several members of Mr Berlusconi's entourage rushed to his aid but he was unable to stand up and had to be carried out of the room.

An ambulance arrived at the centre and a nurse said Mr Berlusconi received treatment.

Shortly after he collapsed, former lower house speaker Irene Pivetti told the audience that Mr Berlusconi was recovering.

"He felt unwell due to the tension, he is very sorry and wants to continue but the doctor has told him not to," Ms Pivetti said.
