No idea, but claims made in parliament (with the exception of calling another member a liar) are privileged. And farage isn’t often there so read into that what you will.
Parliamentary privilege
refers to the special rights and immunities protecting members of a parliament and its proceedings from outside interference, ensuring they can debate freely and perform duties without fear, encompassing freedom of speech (Article 9, Bill of Rights 1689), control over internal affairs (exclusive cognizance), and freedom from arrest in civil cases, primarily applying within formal proceedings like debates and committee hearings, not for statements made outside.
