High wire Helen Skelton: 'Impossible is just a word'

Blue Peter presenter Helen Skelton, who walked a high wire between the chimneys of Battersea Power Station to raise money for Comic Relief, has said she believes "impossible is just a word".

The 27-year-old also confessed she would rather have done her 150m (492ft) high wire walk without a harness, so the wire walking community would take her seriously.

The Red Nose Day challenge, delayed by 40 minutes because of high winds, took her to heights of 66m (216ft).
