Liberal Democrat leader Nick Clegg said the allegations made on Channel 4 News last Thursday had been "extremely serious and distressing to the women involved".
He said: "It is critical they are investigated thoroughly and dealt with properly and they will be.
"But I would like to make one thing crystal clear. I did not know about these allegations until Channel 4 informed the party of them shortly before they were broadcast."
Nobody thinks Nick is the kind of guy who would defend a 'boy's club', but that does not necessarily mean he has handled the issue well.
One of the women who made allegations against Lord Rennard told ITV News that Lib Dem leader Nick Clegg shifted his position on the matter.
Questions for the Lib Dems mount, centred on what senior members knew about allegations surrounding former chief exec Lord Rennard and when.
