Big Ben clock to be turned back to GMT for first time in five years

London landmark to signal end of daylight saving after major repair and conservation project

When do the clocks go back to end British summertime?

All four faces of Big Ben will be put back to Greenwich mean time (GMT) this weekend for the first time in five years.

British summer time (BST) officially ends at 2am on Sunday, and the clocks go back an hour, giving people an extra hour in bed - or partying.
