Duke of Edinburgh officially opens Brighton's i360 tower
The Duke of Edinburgh has officially opened the world's thinnest tall building.
The 531ft (161m) British Airways i360 viewing tower stands on the site once occupied by the entrance to Brighton's ruined West Pier.
Prince Philip was greeted by large crowds as he arrived at the attraction.
The royal party ascended inside the curved-glass pod which gives a 360-degree view of up to 26 miles of the south coast.
The duke was shown the control room and the operating winch before unveiling a plaque.
The i360 holds the Guinness World Record for the globe's most slender tower, with a diameter of 3.9m at its widest point.
Visitors to the attraction ascend to 450ft (137m) and can get views from Bexhill in East Sussex, to Chichester in West Sussex and the South Downs to the north.
The tower first opened to passengers on 4 August but was closed twice in September due to technical problems.

- Trips last 20 minutes and cost £13.50 for adults and £6.75 for children
