Mega-rich Tory chairman Nadhim Zahawi agreed to pay nearly £5 million to settle a tax dispute after being hit with a 30% penalty, it is claimed.
Labour have demanded Mr Zahawi is sacked after new details about the penalty were reported - with an expert saying the sum suggests the MP may have admitted "carelessness".
His financial affairs have been under scrutiny for weeks after the dispute with HMRC came to light.
