Interesting figures:
BREX: 37% (+3)
LDEM: 19% (+2)
LAB: 13% (-2)
GRN: 12% (+1)
CON: 7% (-2)
CHUK: 4% (-)
UKIP: 3% (-)
If those were repeated on the day, under the voting system used in Great Britain:
the first seat in any region would go to Brexit.
the second seat to Lib Dem,
the third to Brexit
the fourth to Labour
the fifth to Brexit
the sixth to Green
the seventh to Lib Dem
the eighth to Brexit
the ninth to Brexit
the tenth to Conservative (and it is only the South East which has 10 seats available. In any other British region the Conservatives would get no seats.
The above calculations are based on the percentages in the polls being repeated evenly across the country. It is possible that SNP & Plaid Cymru would also gain seats in Scotland/Wales.
Unlike 'first past the post' this shows that in most regions, a 37% vote is likely to receive much more than 37% recognition in terms of seats (66% in regions with only 3 seats, 60% in regions with 5 seats)
