Camerons toast the start of their summer break

The couple have returned to the Algarve for their second family break this summer, having already spent a few days away with their three children in the UK.

They started off with a drink in the pretty village of Alvor - known for its narrow cobbled streets and secluded coves - against an idyllic backdrop of sailing boats bobbing gently in the bay.

Mrs Cameron, who chose a black singlet and a flowing floral skirt for the occasion, appeared in relaxed mood, kicking off her flip-flops.

Her husband wore a navy short-sleeved shirt and shorts and a pair of blue espadrilles.

It is their second break this summer - having already spent a few days away with their three children in the UK.

The Prime Minister, a keen cricket fan, also found time to celebrate England’s Ashes victory over Australia on Twitter.

“Congratulations England on regaining Ashes. Thrilling victory. I’ll never forget Botham in 81 & don’t think I’ll ever forget this either,” he posted.

It is the third year in succession that the Camerons have visited the Portuguese coast for their main summer break.

A cafe appears to have been chosen for the annual ritual of the holiday photocall after a series of previous visits to fish markets were widely mocked.

It has been reported that a third break on the Scottish island of Jura, where Mr Cameron’s father-in-law Lord Astor has an estate, could be on the cards.

The Prime Minister is reported to be keen to spend time with his family after a gruelling general election campaign in the spring.

Downing Street has, however, stressed that he will continue to run the country while he is away.

“The Prime Minister is always in charge,” a spokeswoman said.
