Ohuruogu was selected by performance director Neil Black to lead the team at the championships – which run from August 10th to 18th – and he paid tribute to her championship record and conduct amongst fellow athletes.
Black said: "Christine is one of Great Britain’s greatest ever athletes. Her championship record speaks determination and attack, yet her countenance and conduct amongst others makes her one of the most approachable and genuine people many of the team will ever meet.
Ohuruogu will be looking to add to a personal haul that includes a silver in the Olympic stadium last summer to go with the world title she won in 2007 and an Olympic gold from 2008.
“I know she will do a brilliant job of motivating and looking out for her team-mates."
Ohuruogu, who claimed the 400m at the Anniversary Games in London over the weekend, said: "I am very proud to have been asked by Neil to be the team captain at the World Championships in Moscow."
She added: "When he called me up the other week, I thought I was in trouble! I am not normally someone who likes the spotlight, but this is a lovely feeling to be trusted in this role, and it’s nice for myself and my coach Lloyd (Cowan) for the hard work we have put in over the years.
