The rooms are just a third of the entire underground complex used by Churchill between 1940 and 1945

Churchill directed politicians from this bunker during the Second World War and dined there with his wife Clementine and close friend, information minister Brendan Bracken.

Though he disliked it - preferring to maintain a high profile as war leader - he stayed overnight when his military advisers told him it was too dangerous to return to his official residence at 10 Downing Street.

The rooms are just a third of the entire 3,000 square metre underground complex used by Churchill and his cabinet between 1940 and 1945.

And the rooms still preserve many of the day-to-day artefacts including large maps with pinpricks and Churchill's swivel chair.
