since 1980s north-south divide with the exception of london
SE -> prosperous, home ownership, little unionism, white/ rural -> mark Francois safe seat
ethnically diverse areas/ industrial production = labour -> greater Manchester, Wales, Merseyside -> the industrial north
because of FPTP LibDem cant do as well -> Celtic/ artisan regions
marginal seats -> aim to win
region is becoming more important -> Scotland switched from labour to SNP - Torys unpopular that in 1997 they won 0 seats, 2017 SNP won 56/59 seats
Brexit = decisive issue -> Mansfield labour since 1922 but turned tory 2017
