UK police probing claims that former Liberal Democrats official sexually harassed women

British police say they are investigating allegations that a former senior member of the Liberal Democrats party sexually harassed a number of women.

Scotland Yard said Monday it is probing whether criminal activity had taken place following claims that Chris Rennard, a former chief executive of the left-leaning Lib Dems, molested four women in incidents that dated back to 2003.

Rennard denies the claims, while party leader Nick Clegg, Britain's deputy prime minister, faces questions about whether he was involved in a cover-up.

Clegg said Sunday that he had been aware of concerns about Rennard's behavior before, but he had not heard of the specific allegations until they were broadcast by a television program last week.
