Liberal Democrat leader Nick Clegg has admitted that women in the party felt "let down" by the way officials handled complaints against Lord Rennard.
In a statement, he said changes had now been made.
The Liberal Democrats have taken a long, hard look in the mirror since these allegations were made last year and I am confident that the party has changed.
It is clear that a number of women in our party felt let down that the party failed to act on their complaints appropriately. I am determined that no member of our party should find themselves in that position again.
That’s why I immediately appointed Helena Morrissey to carry out a root and branch review of our culture and processes and made sure we acted on her recommendations.
In addition, at my request the Party President and the Federal Executive established a review into our procedures for handling cases such as this to ensure that the party's rules are fit for purpose in the future.
This review has now been completed by a senior barrister who has recommended that we make changes to the current criminal burden of proof and these changes will now be taken forward.
