London Mayor Sadiq Khan has said that he had five armed police officers protecting him outside the ITV studio while appearing on Good Morning Britain.
The 51-year-old told hosts Susanna Reid and Richard Madeley that it "isn't safe" for MPs at the moment and warned that politicians needed to be aware of the effect that words have.
It comes after Sir Keir Starmer and Shadow Foreign Secretary David Lammy were mobbed by anti-vax protestors falsely accusing the Labour leader of "protecting" paedophile Jimmy Savile.
