Labour’s deputy leader Tom Watson has criticised the "brutal" dismissal of Gavin Williamson over the Huawei leak.
Speaking in the House of Commons today, the MP said the matter was not "closed", as Mr Williamson had maintained his innocence.
"In response to receiving the most brutal sacking I can think of, Gavin Williamson has protested his innocence. Therefore this matter cannot be, as the Prime Minister says, closed," he said.
"The essential point here is the Prime Minister has sacked the secretary of state for defence because she believes there is compelling evidence that he has committed a crime.
“But despite that, she does not believe he should face a criminal investigation - where is the justice in that?".
In response to Mr Watson's urgent Commons questions, Cabinet Office minister David Lidington said the government would "cooperate fully" if a criminal investigation took place.
Speaking earlier on the Today programme, Mr Watson said the former defence secretary had "the right to clear his name".
