Double Olympic gold medallist Mo Farah has become the father of twin girls.

The beaming 29-year-old revealed yesterday that wife Tania, who was heavily pregnant during his 10,000 and 5,000 metre triumph, has given birth.

Farah said that he is going to get the girls' names inscribed on his two gold medals once they have decided what to name the twins.

"My wife has been holding on so long and it's great that she held on this long and didn't give birth on the track.

"To have three kids in the family is going to be exciting. If my wife has another two more twins boys, I'll be a happy man.

"I am actually going to get their names on [my gold medals], once we've figured out something with the medals - one on each. And then whatever one was born first gets the 10,000m and the other gets the 5,000m one."

The Somali-born runner competes in a two-mile road race in Birmingham today.
