Lord Rennard has previously apologised if he had “inadvertently encroached” upon “personal space”.
The Lib Dem spokesperson added party leader Sir Ed Davey believes “Rennard should not be a member of the House of Lords” and “that it should be made easier for peers to be expelled from the Lords for serious misconduct”.
In 2013, Lord Rennard, a former party chief executive, was accused by four women of abusing his position for years by inappropriately touching and propositioning them.
The party’s internal inquiry found that there should be no further action against Lord Rennard but requested he apologised. He initially refused but later expressed regret.
The Metropolitan Police also found there was “insufficient evidence” to prosecute the peer over allegations of sexual touching
Lord Rennard subsequently challenged his suspension from the Lib Dems, saying it was against party rules. It was eventually lifted after disciplinary proceedings against him were dropped and the party said this brought “the matter to a close”.
