Andy Murray has encouraged people to turn their lights off for an hour in support of a campaign to raise awareness of climate change.

Edinburgh Castle, the Scottish Parliament and the Falkirk Wheel are some of the Scottish landmarks which will turn their lights off for the Earth Hour campaign.

The event will take place at 8.30pm to 9.30pm on Saturday, with organisers encouraging members of the public to join in.

Last year's event, organised by the charity WWF, saw more than 700 landmarks around the world switch off their lights, including Christ the Redeemer in Brazil, France's Eiffel Tower and more than 30 Unesco World Heritage Sites.

Glasgow Cathedral, the Kelpies sculptures, Eilean Donan Castle and Linlithgow Palace will also turn off their lights on Saturday.

Ahead of the event, Andy Murray said: "Our planet is incredible and it’s up to us to make sure we take care of it for the next generation.

"That might seem like a really big job, but one simple way to show your support and help protect our planet is to take part in WWF’s Earth Hour.

"It’s fun, but there’s a serious message too, together we have the power to make real change happen.

"So whether you enjoy a candlelit dinner at home with friends, or a fun night of stargazing with the kids, switch off at 8.30pm for one hour on Saturday, March 19 and be part of something big."

Great British Bake Off star Flora Shedden has also aupported the campaign, and has created a special Earth Hour recipe for a candlelit dinner.

She said: "I’m delighted to be supporting Earth Hour and hope as many people as possible get together with family and friends on Saturday, March 19 and hold a candlelit dinner party and share selfies on social media.

"I’m passionate about food and about using the rich variety of locally grown fruit, vegetables and meats available here in Scotland. I will certainly be taking part in Earth Hour and taking the opportunity to try out a few new recipes for my book.”

WWF Scotland director Lang Banks said: "It’s brilliant to have Andy Murray and Flora Shedden lend their support to Earth Hour.

"Every year I’m amazed and delighted at how the people of Scotland get behind Earth Hour. From schools and businesses to politicians, celebrities and iconic landmarks, we’ve received an amazing level of support and it’s been great hearing about all the different ways people plan to celebrate the hour.

"Lights around the world will go out for one hour today, but the need to take action extends throughout the year.

"For many people the symbolic event is a catalyst for change, with more than four-fifths of those who took part in Earth Hour last year feeling inspired to do more to help protect the planet."
