In Britain, there's nothing new about a Whopper on the side of a bus, especially when it comes to election time. 

However, that hasn't stopped Burger King and BBH providing a fresh take on the genre with their innovative campaign. Parked outside the UK's parliament, a bus emblazoned with an election-themed ad for the chain's signature burger got the country talking, with a huge amount of press and social media coverage.

Speaking to LBB, BBH's chief creative officer Ian Heartfield said "This is how advertising is meant to work. Phil & Stu came up with a killer idea, a brave client didn’t hesitate to approve it, we got it made and out onto the streets in next to no time, the nation started talking about it.  Job done."
