Double Olympic champion Mo Farah has given the Commonwealth Games a major boost by announcing he will compete in Glasgow this summer.

Farah wrote on Twitter on Monday "I will be running in the Commonwealth Games this year..!! See you in Glasgow..!! Shabba....!!"

With Olympic heptathlon champion Jessica Ennis-Hill missing the games as she is expecting a baby, Farah will be the most high-profile British athlete in Glasgow.

Sprint star Usain Bolt still has not confirmed whether he will be running at the Commonwealth Games, which takes place from July 23-Aug. 3.
