Perhaps these seat reductions which come at the expense of mainly non-Tory areas will readdress that - that's what they're hoping, anyway.
Not as much as they'd hope. Someone's clearly not explained 'differential turnout' to the government. No boundary change will make voters in Liverpool Riverside get to the polling station at the same rate as voters in Tatton or Witney meaning that it will
always take, on average, fewer voters to elect a Labour MP under a single-member constituency system like FPTP or AV.
