Bush backs McCain for president :

President George W Bush has praised John McCain's service and leadership in a speech to the Republican convention.
Speaking via video-link from the White House, he told delegates in St Paul, Minnesota, that Mr McCain was "a great American and the next president".
Mr McCain is due to be nominated on Thursday as the party's presidential candidate for November's election.
The main talking point so far has been the news that the teenage daughter of Mr McCain's running mate is pregnant.
Alaska Governor Sarah Palin, chosen as the vice-presidential nominee last week, announced on Monday that her 17-year-old daughter, Bristol, would have the baby and marry her boyfriend.
In his eight-minute address, Mr Bush described Mr McCain as a president ready to make the tough decisions needed "in a dangerous world".
