How important will tactical voting be in this election?
General estimates suggest a few dozen seats can change hands purely as a consequence of tactical voting. In by-elections we’ve seen it work for Labour. Take Mid Bedfordshire in 2023: after the resignation of Nadine Dorries, Labour overturned a Tory majority of 24,664 to win with 34 per cent of the vote, aided by tactical votes from would-be Liberal Democrat and Green voters.
