The Olympics are just over two weeks away, but there are real fears that the biggest sporting event in the World could become a complete washout.
The downpours, that have ruined the summer of 2012 so far, are beginnning to cast doubt over whether there's a plan in place to cope with the wet weather.

Live Nation said the fraudulent tickets had been created by parties preying on music fans who did not use official ticket outlets.
Individuals and organisations which look after war memorials are being encouraged to apply for free "SmartWater" kits.

Nancy Treves from the War Memorials Trust says that it is vital our war memorials are protected, as they provide unique records of the men and women who have made the ultimate sacrifice.

It aims to protect the nation's war memorials by marking them with 'SmartWater' - a traceable liquid that should deter metal thieves.
