British Prime Minister David Cameron (left) with Conservative Parliamentary candidate, Giles Watling, during their work visit to improve the sea defences at Clacton-on-sea, east of London, yesterday. Clacton is the seat of Conservative member of parliament Douglas Carswell, who resigned from the party to join the eurosceptic UKIP. Carswell is expected to be re-elected on October 9, threatening a major embarrassment for Cameron.
