The first Olympic event, women's football, kicks off in Cardiff on Wednesday, July 25 as 30 miles of games lanes open across London, The Huffignton Post said.

Team GB women's football side are to take on New Zealand in Cardiff's millenium stadium, marking the start of the 18-day sporting spectacular.

Also, Cameroon play Brazil after the GB game.

Culture Secretary Jeremy Hunt will join Gillan in the Welsh capital for the first sporting event of London 2012.

Every very goal scored by Britain's men's and women's football teams in the Olympic group stages will see 50 footballs donated to charity.

Wembley Stadium, a venue for both the London 2012 and London 1948 Games, is making the gesture as part of the Football Association's Olympic legacy plans.
