Theresa May has promised to "look back" at the claims
The British Prime Minister has been accused of failing to act on warnings about historic claims of a Westminster sex scandal cover-up.
Labour Party MP Lisa Nandy claimed she told Theresa May - then the British Home Secretary - years ago about allegations Tory whips had "used information about sexual abuse to demand loyalty from MPs."
Speaking at Prime Minister's Questions, Ms Nandy said: "I brought that information to her in this House and I warned her at the time that unless real action was taken we risked repeating those injustices again today."
"On three occasions I asked her to act and on three occasions she did not," she said.
"So can I ask her - in this of all weeks, for the fourth time, will she finally take concrete action to tackle this?"
Ms Nandy also tweeted a question she asked Mrs May in July 2014, about the child sex abuse inquiry.
In it, she highlighted the claim by an ex-Tory whip made in a 1995 documentary that his office routinely helped MPs with scandals, including those "involving small boys," during the 70s.
Mrs May responded on Wednesday by promising to "look back" at the interventions.
"I will say to her that I am very clear that the whips office - I hope this goes for all whips offices across this House - should make clear to people that where there are any sexual abuse allegations that could be of a criminal nature that people should go to the police,” she said.
"It is not appropriate for those to be dealt with by whips offices - those should go to the police.
"That continues to be the case."
Her response to the 2014 question was a hope that political parties should not be "outside the scope" of the inquiry, now led by Professor Alexis Jay.
It comes as a series of fresh sex assault and harassment claims brew in Westminster.
A whistle-blower helpline will be "strengthened" and told to recommend all serious allegations to police as a result, the Government announced on Monday.
