Colombo: Sri Lanka's National Olympic Committee said it did all that it could to win the majority support for hosting the 2018 Commonwealth Games and doesn't know why it lost the race to Australia's Gold Coast.

The Chairman of Sri Lanka's National Olympic Committee Hemasiri Fernando, speaking to local media on the telephone from St Kitts, Nevis in the West Indies, said Sri Lanka was confident ahead of the vote.

The 71 member nations voted 42-27 in favour of Gold Coast over Sri Lankan city of Hambantota.

"You see this was a secret vote. So things can change in the final analysis. We have no control on it," Fernando said.

Fernando said Sri Lanka had fared better than Nigeria's Abuja which polled only 20 votes when they lost to New Delhi the right to host last year's Games.

Sri Lanka ran a massive publicity campaign leading to the bid. The southern coastal district is the home of the President Mahinda Rajapaksa.

The President's son and parliamentarian Namal and the island nation's Central Bank governor Ajith Cabraal co-chaired the bid with political backing.

The Games bid was projected as 'a life changing' one to rebuild Hambantota after the Tsunami devastation of 2004.
