Barack Obama's team are adding some glamour to the US presidential campaign by offering donors a dinner date with Hollywood heartthrob George Clooney.

Donors who support Obama's race for office are being given the chance to win a seat at the A-list dinner attended by a selection of celebrity guests as well as Obama and Clooney.

The once-in-a-lifetime meal, which is expected to generate up to $6m (£3.7m) for the president's re-election campaign, will be held at the actor's Los Angeles home on 10 May.

For as little as a $3 donation, members of the public will get their chance in a lucky draw to win a seat at the star-studded fundraiser.

Those who want to buy a definite place at the table will have to stump up $40,000 a person.

The offer is open only to people who are eligible to vote in the US election in November.

The 50-year-old Ocean's Eleven star's support for Obama's re-election against rival Mitt Romney is no secret.

Clooney, who met Obama before his arrest at a protest outside the Sudanese embassy in Washington in March, said: "I'm a Democrat and I'm a supporter of the president so I hope he has a very good ... successful election."

Obama's campaign website tells supporters: "George Clooney is doing his part to help re-elect the president but he knows that it's grassroots supporters like you who will decide this election,"

The US presidential election will take place on 6 November.
