EU referendum, brexit and the aftermath

I would cite examples of Cameron's laziness as being: doing little on the Scottish referendum until the last minute (and relying on others - including the likes of Gordon Brown - to bail him out); doing pretty much the same for the Brexit referendum all the while nonchalantly claiming to his EU counterparts that everything was going to be ok. Someone who wasn't lazy would have realised that there was important and urgent work to be done far ahead of the deadlines. It wasn't for nothing that he was known by some as the "essay crisis" Prime Minister. And by some accounts he used to spend most of his days playing Fruit Ninja :)

One of many examples:

Future historians will probably be arguing for years to come whether
he really needed to promise an In/Out referendum on the UK’s
membership of the EU, as his defenders claim, to protect his flank
against Ukip. What is not in doubt is that Cameron believed he could
win it. It became a cliché to call him an “essay crisis” prime
minister – a gibe that must have seemed meaningless to millions of
people who never experienced the weekly rhythms of the Oxford tutorial
system. And yet he never really managed to banish the impression of
insouciance. The image of chillaxing Dave, the PM so cockily laidback
that he left everything until the last minute, may be a caricature,
but my guess is that it will stick.
