David Cameron has been British PM since May 2010 and won a second term in May 2015 with an all Conservative government (his first government was a Coalition with the Liberal Democrats). That second term was won with a much larger majority (331-232) than predicted by polls, probably because the polls under-estimated the (then) unpopular proposals by Labour Leader Millibrand (now replaced by the extremist Corbyn!). An independent inquiry into the polling suggested that the polling methods resulted in conservative voters being under-represented. The 72.7% who voted on the EU referendum exceeded the proportion in the May 2015 election (66.4%) and the 1975 European referendum’s 64.62%. Reports indicate that those who voted to leave appear to have comprised a high proportion of lower-middle income groups.
