But sources say officers are concerned about activities by anarchist groups ahead of the big day and carried out pre-emptive raids on squats in London this morning, in which 20 were arrested.
Sky sources said a separate operation saw three more arrested tonight in Brockley, southeast London, and a large guillotine seized. It is thought protesters were planning to use it to slice heads off effigies
Just how real was this guillotine?
(Note - these were anarchists not, anti-terror raids)
Good luck to all the officers and agents working the beat in London tomorrow.
