UK's Cameron says to rule on extra London airport capacity by year-end

British Prime Minister David Cameron said on July 1 he would take a decision by the end of this year on how London's airport capacity will be expanded and would study a recommendation to build a third runway at Heathrow.

Cameron was speaking after a government-appointed commission said a third runway should be constructed at London's Heathrow Airport in a report set to create a political headache for the prime minister. 

"A decision will made before the end of the year," Cameron told parliament. "It is important now that there is a very detailed report that we study and are very clear about the legal position. If we say anything now before studying the report, we will endanger whatever decision is made."
