Olympic medallist Rebecca Adlington has been announced as an "ambassador" for the Commonwealth Games in Glasgow.
The swimmer, who also won two medals at the Delhi Games two years ago, joins Scottish cyclist Sir Chris Hoy in the role.
She said: "It's a privilege to be involved as an ambassador for the Glasgow 2014 Commonwealth Games and I'm thrilled to be able to voice my support to the next major sporting event coming to the UK."
Adlington added: "The huge success of London 2012 will only increase the excitement and interest towards the Games and I can't wait to be part of the journey to 2014."
She will help launch the official mascot at an event in Glasgow on Thursday.
Lord Smith, chairman of Glasgow 2014, said: "Rebecca is Great Britain's greatest ever swimmer and she is such a well-known personality across the sporting spectrum.
"Alongside Sir Chris, Rebecca will promote the Games and help ensure as many people as possible make the most of Scotland's largest ever sporting and cultural event."
Adlington, from Mansfield, Nottinghamshire, has four medals from Olympic Games in Beijing and London.
