London 2012: Weather testing the Olympic torch

The organisers of the London Olympic Games torch relay have gone to extreme lengths to make sure the weather doesn't snuff out the flame as it travels round the UK.
It's been taken to the summit of Mount Snowdon where it was exposed to the blustery Welsh winds.
The BBC has been given exclusive footage of the testing, which shows a lit London Olympic Games torch for the first time in public.
