Defence Secretary Gavin Williamson was dramatically sacked by the Prime Minister.
Defence Secretary Gavin Williamson’s sacking by the Prime Minister follows days of political drama surrounding the leak of information from the UK’s National Security Council.
Here is how the leak developed into a major Government inquiry:

April 24 – The Daily Telegraph newspaper reports that the Prime Minister has agreed to allow Chinese telecoms giant Huawei to help build Britain’s new 5G network despite security concerns raised by Cabinet minsters at the meeting.
Labour demands an official investigation into the leak from the highly secretive council.
April 25 – Dominic Grieve, chairman of the Parliamentary Intelligence and Security Committee, says the leak is “deeply worrying”.
Home Secretary Sajid Javid says it is “completely unacceptable” for any minister to release sensitive information and that it should “absolutely be looked at”.
Gavin Williamson and Foreign Secretary Jeremy Hunt publicly deny they are responsible.
In a statement, Mr Williamson says neither he nor any of his team had “divulged information from the National Security Council”.
April 26 – An ultimatum is reportedly issued to ministers over the leak of the secret discussions.
Reports emerge that Cabinet Secretary Sir Mark Sedwill has demanded ministers in attendance at the NSC meeting confess or deny if they were behind the leak.
Downing Street refuses to say whether an inquiry is under way, despite calls for police to become involved.
Sources close to International Trade Secretary Liam Fox and International Development Secretary Penny Mordaunt also deny they were involved.
April 27 – It is reported that members of the Cabinet are expected to be summoned for interviews as part of a formal inquiry headed by Sir Mark Sedwill.

April 28 – Jeremy Hunt says he has been questioned by officials as part of a leak probe and is prepared to hand over his phone.
