The body that sets the rules for international football has approved the use of goal-line technology. The International Football Association Board gave the goal ahead for two systems – one involving cameras and one that uses a

sensor

in the ball. The head of the world football Sepp Blatter said he came round to the idea after England had an important goal

disallowed

during the 2010 World Cup. Fifa secretary general Jerome Valcke says the technology could be introduced for the next World Cup in Brazil.

"We Fifa have decided to use the system at the Club World Cup next December in Tokyo, and that, if it is working, at the Confederations Cup 2013 and the World Cup 2014."

Over the past decade, the British army has been at war, fighting on two fronts: in Iraq and Afghanistan for long stretches. The smaller army of 2020 won't be big enough to do that. It will be split in two: a reaction force made up of regular troops, highly trained and ready to deploy

at short notice

, and an adaptable force that will carry out ceremonial roles, as well as meeting long-term commitments like defending the Falklands. The army of 2020 will be more reliant on

reservists

, no longer an add-on but an integral part of the army.
