David Cameron looked casual and relaxed as he enjoyed a sunny break in the Cornish village of Polzeath.

The Prime Minister, who has received a painkilling injection after complaining about a "phenomenally bad back", was pictured visiting the small beach village in north Cornwall with his wife Samantha.

The couple were dressed in complementary blue tones, with Mr Cameron opting for a navy polo shirt and matching shorts, while his wife wore a denim blouse teamed with beige chino shorts.

Mr Cameron showed few signs of the pain he has been suffering, appearing relaxed with his top button undone.

Both wore flip flops, with Mrs Cameron's right-ankle tattoo in full view, as they were photographed on a pier walking away from a café .

It is not the first time the Camerons have visited Polzeath. Last year they braved blustery showers to have lunch at a beach-front café where they shared a bowl of local mussels on the terrace during a gap in the rain.

The couple have regularly visited Cornwall for the last few summers. It was here that their youngest daughter Florence was born in 2010.

One of Florence's middle names, Endellion, is comes from St Endellion, a village in the north of the county near to where the family had been staying when she was born.
