David Cameron has sent a good luck message to the England football team ahead of their first World Cup match tonight.
The Prime Minister admitted that the draw - which sees Roy Hodgson's players take on Italy - was "tough", but stressed the country was behind them.
"On behalf of the whole country I want to wish the England team the very best of luck for the World Cup. There is nothing like a World Cup to bring our country together," Mr Cameron said in a video message for FATV.
"All of those club rivalries fade away and we'll all be joining together, gathering round the television, sitting in the pub - which will be open late - and cheering on our national team.
"It's a tough draw - some say it couldn't be tougher - but we are right behind you every step of the way. Go for it."
The flag of St George is to be flown over 10 Downing Street for England's matches in Brazil.
It will be raised after the Trooping the Colour ceremony this afternoon, and will be flying for the later matches against Uruguay and Costa Rica, as well as any subsequent games if the team progresses to later rounds.
The flag of St George was also on display during the World Cup finals of 2006 and 2010.
