Brighton Pier before and after Feb 2014 storm

Footage shows how Brighton's West Pier looked in 2010 and after rough seas caused part of it to collapse into the sea in February 2014.
A number of its main supports on the eastern side appear to have been washed away, splitting the former pavilion into two sections.
Part of the derelict Grade I listed pier's eastern side also crumbled into the sea in January 2013, following cold weather conditions.
