Nor has it ever hit the high of 1.75 euro to the pound, also under a Labour Government in April 2000.
Amazing what you can cherry pick.
However since the referendum the pound has consistently traded at a level 15% lower than before the vote.
Every day, every week, every month.

Immediately prior to the result (June 23 2016) the rate was 1.3039.
85% (100% less 15%) of 1.3039 is 1.1083 The pound fell below this level briefly in Oct/Nov 2016 and again in August/Sept 2017

So NOT 15% lower, every day, every week, every month. Hardly even two full months out of fifteen.
