I'm sure his wife thought differently when she discovered his affair. I've not met either of them but at the end of the day they're both politicians so not 100% trustworthy. There's not much between them even if their ideology is different. On drink and drugs: Ken-Likes a Whisky, Boris prefers Cocaine On political cohesion: Ken was kicked out off Labour's National Executive for being radical, Boris was sacked from the Tory front bench for lying On misquotes: Ken misquoted on the 'Nazi' affair and Boris on the 'Water Melons and Piccannini' speech On love life: Ken has kids out of wedlock, Boris got caught The only major difference I can see is that Ken (who was born and brought up around the corner) has run London, pretty well IMO and Boris has no track record and was born in the US and educated in Brussels.
