25 mountaineers are braving the elements to search for missing climbers

A 25-strong search team will brave severe sub-zero temperatures and the risk of an avalanche in the continuing hunt for two climbers missing for a week in the Scottish Highlands.

Rachel Slater, 24, and Tim Newton, 27, failed to return from an outing on Ben Nevis last weekend and treacherous conditions have hindered air and ground searches on Britain's highest peak.
