SCOTTISH cycling champion Callum Skinner has backed a charity campaign.

Several of the Commonwealth Games venues will be turning off the lights to support WWF's Earth Hour on Saturday.

The Sir Chris Hoy Velodrome will go dark, along with the Emirates Arena and Commonwealth House.

Callum said: "Getting on your bike for shorter journeys helps cut pollution. I'm delighted Glasgow 2014 is getting behind WWF's Earth Hour."

Buildings and landmarks across Scotland will switch off their lights at 8.30pm to demonstrate their support for people and wildlife threatened by climate change.

David Grevemberg, chief executive of Glasgow 2014, said: "We hope to encourage others to think about ways they can make positive and lasting changes in the way they use resources now and in the future."
