Labour MP Bridget Phillipson urged the Lib Dems to launch an independent investigation into the allegations.
This series of allegations are too serious to allow the Liberal Democrats to investigate themselves.
The Liberal Democrats must urgently commission an independent investigation of their party. It simply will not do for them to attempt to brush off these serious allegations by treating them as an internal party matter.
Nick Clegg and other senior Liberal Democrat MPs and officials must come clean about what they knew and what action was taken about these serious allegations of sexual harassment.
Getting to the truth and learning lessons must be the priority.
