Boris Johnson has been dealt a huge Partygate blow with the resignation of his independent adviser on Ministerial Interests.
Lord Geidt, whose advice to the Prime Minister was humiliatingly ignored by Boris Johnson, left after he admitted he could not effectively act as an independent judge on the Prime Minister's behaviour.
Geidt was grilled by MPs earlier this week about whether the the Tory leader broke the ministerial code when he was fined over Partygate.
