The organisers for London 2012 have revealed that there are up to 400,000 tickets yet to be sold for the Games.
The highly-anticipated event has been dogged by problems surrounding ticket sales in the build-up to this summer's Olympics.
It has now emerged that thousands of tickets are yet to be snapped up by spectators, with just one week to go until the first event.
Organisers have also warned individuals that they may need to take wellington boots with them to certain equestrian and rowing events due to waterlogging.
