More than 50 British MPs have been charged with various sexual offences, The Times reported.

Parliament's independent complaints system registered 70 complaints against at least 56 legislators, the newspaper said.

Charges range from harassment to more serious offenses such as rape and paedophilia. The investigation comes after Conservative MP Imran Ahmad Khan was found guilty last week of abusing a 15-year-old boy in 2008.

Most of the complaints are not confirmed. An independent parliamentary investigation is currently underway.
