Blue Peter presenter Helen Skelton has walked a tightrope 66m (216ft) high between the chimneys of Battersea Power Station in aid of Comic Relief.
The 27-year-old BBC children's presenter covered the 150m (492ft) stretch on a high-wire above the south London building in just 11 minutes.
The challenge had been delayed by 40 minutes because of high winds.
