The MP for Bassetlaw has called on the Prime Minister to resign following the revelation that David Cameron and his wife owned shares in the Panamanian trust set up by his late father.
Labour's John Mann insisted Mr Cameron should resign and labelled the PM a "hypocrite".
The Treasury Select Committee member wrote on Twitter: "Cameron has been less than honest. He should resign immediately. Most decent people would expect nothing less."
Mr Mann added:
The number of people coming forward with allegations about historic child abuse is set to reach "many tens of thousands", a local MP has warned.
Labour backbencher John Mann, who has been campaigning on the issue, said the state "can't deal with" the volume of claims that are being made.
He insisted there was too much focus on who was going to run the Government's troubled inquiry into paedophile activity, and suggested a national institute needed to be created to make progress.
His comments, on BBC Radio 4's Today programme, come with the shape of the wide-ranging probe ordered by Home Secretary Theresa May still mired in uncertainty.
Two candidates for chair - former judge Baroness Butler-Sloss and ex-Lord Mayor of London Fiona Woolf - have already had to stand aside over their establishment links.
But Mr Mann said there had been too much emphasis on individuals.
