Video: Robbie Williams gives viewers the middle finger during his performance at the #WorldCup opening ceremony

Robbie Williams has sparked outrage after appearing to give the finger to the camera during a performance at the World Cup opening ceremony.

Football fans exploded on Twitter after noticing the ageing singer stick his middle finger up when leaving the pitch following a performance of his hit song 'Angels' as part of Thursday afternoon's proceedings. Twitter users were left stunned by Williams' antics with some blasting him for a 'lack of morals' and calling him 'desperate for attention'. Thousands of revellers packed inside the sold-out stadium to witness the dazzling opening ceremony - seen by an estimated one billion people worldwide.
According to experts, Williams risks facing arrest and a fine for his one-finger gesture, if it is proved it was meant as an insult. Russia's administrative code allows prosecutors to take offenders to court and be punished for outraging public decency - punishable with a fine of up to £6,000. One legal source in Moscow said: 'It needs to be proved that the gesture was intended to be an insult and an expert has to testify in the court that it was an insult.'
