David Cameron and Nick Clegg marked the first anniversary of the coalition government yesterday with a visit to Stratford’s Olympic Park.

The prime minister and his deputy were at the site on the day the 2012 handball arena became the third venue to be completed.

They also used the visit to announce a new �60 million package of measures designed to tackle youth unemployment — and insisted the bond between their two parties was still strong.

“What I’d say about the coalition a year on is that the reason we formed a coalition is as strong today as it was a year ago,” said Mr Cameron.

“Which is that this country has got some really deep problems that we need to deal with.”

He and Mr Clegg went on to inspect work by Olympic apprentices on the 6,500-capacity handball arena.

Mr Cameron added: “That this great venue has been completed on time and within budget is testament to the hard work, expertise and skills of the Olympic Park workforce.

“We are on track to stage a fantastic Olympic and Paralympic Games in London next summer.”
