Royal Mail postboxes painted gold to celebrate Britain's Olympic winners in the region will not be returned to red.
The company said 110 boxes painted gold across the UK will also have plaques attached, naming the successful athlete and their achievement.
The Royal Mail said it believed it was the first time it had permanently changed the colour of its distinctive red postboxes.
They were painted gold to mark gold medals won by Britons in the Olympics and Paralympics and have become "cherished local landmarks".
– Moya Greene, Royal Mail Chief Executive
We are delighted at the way people took to this simple idea.
The gold postboxes gave communities even more opportunity to mark the successes of Team GB and Paralympics GB, and became a part of local celebrations of London 2012 across the UK. I am pleased to confirm that these postboxes will be kept gold permanently.
