Tonight Newsnight is hosting a four-way debate – with the BBC giving the Greens the fourth seat despite UKIP currently polling higher. During the debate Ken will no doubt make his usual magic money promises and claim that Boris plans to kill all London’s first born sons. So, to make it easy for you to keep track of Ken’s unfounded claims during the debate, the NotKenAgain.com website has created a positive fun little game they’re calling KEN-GO.
