Cameron dashes to be by dad's side following stroke
Prime Minister David Cameron is travelling to France to be with his parents after his father, Ian, suffered a stroke on holiday.
Mr Cameron has previously described his father as a "huge hero figure".
The 77-year-old was born with both legs deformed, and endured repeated operations in an attempt to straighten them and ease his pain.
However, despite his disability, he forged a successful career as a stockbroker.
In an ITV interview before the General Election, the Tory leader said: "My father is a huge hero figure for me.
"He's an amazingly brave man because he was born with no heels - quite a disability. But the glass with him was half-full, normally with something alcoholic. I think I got my sense of optimism from him."
Ian and Mary Cameron - a former magistrate - live at the family home in Peasemore, Berkshire.
Deputy Prime Minister Nick Clegg will fill in for Mr Cameron fielding questions in the Commons at noon.
A Downing Street spokesman said: "The Prime Minister was informed this morning that his father, Ian, is seriously ill after suffering a stroke and heart complications while on holiday in France.
"After talking to doctors at the hospital, the Prime Minister has decided to fly to be with his father and mother Mary.
"The Deputy Prime Minister will stand in for him at PMQs later today."
