David Cameron's mother has apparently signed a petition against spending cuts in his constituency.

Retired magistrate Mary Cameron, 81, has put her name to a battle to save dozens of children's centres due to be closed by Conservative-run Oxfordshire County Council, according to the Daily Mirror.

The Prime Minister previously wrote to the local authority in his capacity as MP for Witney expressing "disappointment" at planned cuts to museums, libraries and day centres for the elderly.

But Tory council leader Ian Hudspeth hit back, saying the curbs were the result of reductions in funding from central government.

Mrs Cameron reportedly signed the petition while she was visiting her son.

She told the newspaper: "My name is on the petition but I don't want to discuss this any further."
