Williams development driver Susie Wolff has criticised proposals by Formula 1 supremo Bernie Ecclestone for an all-female championship.

Ecclestone is reportedly considering the idea of a women-only category, but Wolff has suggested that the idea has several flaws.

Wolff is quoted by Auto Week as saying: "First of all, I don't know where you'd find a full grid of female drivers who are good enough.

"Secondly, I have raced my whole career in motorsport as a normal competitor. Why would I ever look for a race where I was only competing against women?

"I can hand on heart say it would not interest me at all to win such a race. I would rather not be in the race because what am I winning? A race where they've just looked for any girl to make a grid up."

Wolff made her F1 debut when she drove in the first free-practice session at last year's British Grand Prix.
