General Motors expected to report fall in profits

General Motors, which last year regained its position as the world's largest car maker, is expected to report a drop in quarterly profits.

The firm's biggest problem is its business in Europe which is losing money.

However, this week GM reported a 6% slide in July sales as high US unemployment and weak consumer confidence kept would-be buyers on the sidelines.

So is GM's revival under threat?
