One of Big Ben's newly restored clock dials has been unveiled after more than a year of work to reveal a face with blue hands and numbers - not black.
The North Dial, which faces over Whitehall and the Embankment, is now fully visible after the surrounding scaffolding was removed and some tourists have been left surprised at the new colour.
A clock face of Big Ben is one of the world's most iconic images and anyone with a photograph of the North Dial will most likely have seen black not blue when taking their snap - unless it was before the 1930s.
