Athletes are sleepy, hungry and need to pee. Could we get to the Olympic Village please?

An embarrassing shortage of security guards, fears over airport queues and questions about the capital's creaking transport system have overshadowed preparations for the Games. And two stories from American and Australian athletes did little to dispel the sense of farce. US 400m hurdler Kerron Clement, twice a world champion, claimed he spent four hours on a bus after the driver got lost on the way to the London 2012 Olympic village. Games organisers are expecting a busy day with hundreds of athletes checking in but it's not all been smooth running according to Clement - who takes on Dai Greene, Great Britain's current world champion, in the 400m hurdles next month. "Um, so we've been lost on the road for 4hrs. Not a good first impression London," he tweeted. "Athletes are sleepy, hungry and need to pee. Could we get to the Olympic Village please?"
