Colin Farrell is preparing to walk his gay brother down the aisle when he marries later this year.

The actor will be best man when Eamon Farrell ties the knot with his partner Steven in a European ceremony.

And Eamon has blasted the British government for forcing him to travel abroad to marry.

Gay couples can make their relationships legal in the U.K. with same sex civil unions, but still cannot marry in the same way as a man and woman.

Eamon says, "We have to get married abroad. It's absolutely terrible. We have to go somewhere legal, which narrows it down to about five countries.

"I want to be able to get married. The Government's paper on civil unions is only for gay people. If you're straight, you can't have one. So that's not fair either.

"If you want a civil union you should be able to do it, if I want to get married I should be able to do it."
