US President George W Bush is visiting Denmark ahead of the G8 talks in Britain.He will spend less than a day in the country, where he is expected to thank staunch ally Copenhagen for keeping 420 troops in southern Iraq. Bush will also be holding talks with Danish Prime Minister Anders Fogh Rasmussen. The President spent the evening with Denmark’s Queen. This is the fourth time Bush has visited Europe since his re-election in November last year, and his first time in Denmark since he came to power in 2001. The US president’s visit was also greeted with protests by some 250 youths from the extreme left. They held up traffic, burning the American flag and an effigy of George Bush. More than 2,000 police officers were deployed for the demonstration in one of the biggest security operations Denmark has seen.
