Britain is well known for its elitist class of Eton educated politicians who spent their formative years at University lording it up on the back of mum and dad’s cheque book, before coming a cropper and having to pull one’s socks up so that Papa could find them a suitable job in the real world, probably on the London stock exchange.

This venerable class of in-bred aristocracy, who carry with them an air of entitlement and behave like Stannis Baratheon in that they have a ‘birthright’ to lead this country have been the topic of many a British film, but The Riot Club is different.

Directed by Lone Scherfig its a movie based on a play called Posh written by Laura Wade and takes inspiration directly from the fop-haired, waistcoat wearing real-life posh boy’s super, secret Bullingdon Club, which Prime Minister David Cameron, London Mayor Boris Johnson and current Chancellor George Osborne have all been members of.

The Riot Club opens on September 19.
