Harry, Zayn, Liam, Louis, Niall ... and Dave. The prime minister stars as the extra member of Brit Award winning boy band One Direction by joining them for their new charity single.

The five then dance around the prime minister as he stands waxwork like with a fixed smile. Sadly, or thankfully, Cameron does not join his younger co-stars in the pelvic thrusting in Downing Street.
