I thank the right hon. Lady for her letter. As she knows, the Government and Ministers do not comment on security clearance, but the insinuation in her letter that No. 10 is somehow in the grip of a Kremlin mole is frankly ridiculous, even by the standards of the loony left. What is troubling is that the leader of the Labour party sided with the Kremlin when it denied responsibility for the nerve agent attack in Salisbury in 2018—one more reason why this Labour party, under this leader, can never be trusted with Britain’s security.
