Mr Strauss-Kahn has demanded to be questioned over the alleged ring, hoping it will clear his name

Dominique Strauss-Kahn is to be questioned next week by police investigating an alleged prostitution ring in northern France, officials say.

Mr Strauss-Kahn has been summoned for questioning on Tuesday and can be held for up to 48 hours without charge.

He resigned from the International Monetary Fund last May when charged with raping a New York hotel maid.

Although the case was later dropped, it ended his ambitions to run for the French presidency.

A French inquiry into attempted rape claims brought by writer Tristane Banon against Mr Strauss-Kahn was also dropped.

But he still faces a civil suit in the US by his alleged victim in New York, Nafissatou Diallo. Mr Strauss-Kahn has always denied any wrongdoing.
