The new chairman of Parliament’s Intelligence and Security Committee has condemned Downing Street’s attempt to impose its “preferred candidate” to lead the

Mr Lewis was expelled from the parliamentary Conservative Party on Wednesday after securing the prestigious ISC chairmanship with the support of opposition members.

In a statement, he said that the 2013 Justice and Security Act explicitly removed the right of the prime minister to choose the ISC chairman and gave it to the committee members.

In a further blow to the Prime Minister, Mr Lewis’s Conservative association declared its “full support” for the
