Re: So, to sum up. . .
It wasn't quite "a record turnout of 72%" was it? I mean a quick look at Wikipedia (https://en.wikipedia.org/wiki/List_of_United_Kingdom_general_elections) shows that since 72% hasn't been a record LOW turnout since Tony Blair's time. Between the second world war and Tony Blair's election in 1997, yes, 72% was a record LOW turnout matched by that which elected Edward Heath in 1970, with the average for the period being 76.6% and the highest being 83.9%
