Carol Vorderman has said she is sad to be quitting Loose Women.

The former Countdown star has been a panellist on the daytime talk show for three years, but announced her intention to leave because, she said: "I just can't do it all."

The 53-year-old told the Daily Mirror: "In the first two years on Loose I did over 100 days a year but in the last year I have only managed just over 20 days.

"I kept having to cancel due to other work."

The Pride of Britain host said her time is taken up with writing educational books, her maths website and other television commitments.

"I am very lucky woman," she said. "It is a time in my life to make big decisions."
