Liberal Democrat president Tim Farron says his party needs to answer "serious questions" about who knew that its former MP, Sir Cyril Smith, faced allegations of sexual assault.

Police are investigating allegations that the former MP for Rochdale, who died in 2010 aged 82, sexually abused boys at homes and hostels in the town.
