Live: UK prime minister takes questions from MPs

UK Prime Minister David Cameron answers questions from MPs after a difficult week in office.

He published a summary of his tax returns following the leak of documents from Panamanian law firm Mossack Fonseca; they revealed that his father's investment fund was a client. The Panama Papers have led to a series of revelations surrounding other high-profile clients.

In addition, Labour has called for Culture Secretary John Whittingdale to withdraw from press regulation decisions after news of his relationship with a sex worker.

Four newspapers knew about the relationship, which ended in 2014, but decided not to publish the story.
