Good morning. The UK general election is on Thursday, yet about one in eight people have still not decided who they are going to vote for. The polls heavily suggest Labour are on course for a historic victory, but the scale of the Conservatives' defeat - from heavy to catastrophic - may be decided by the large group of as-yet undecided voters.

Labour are projected to win 428 seats, giving the party a stonking majority of 102. The Tories are expected to fall to just 127 seats, and some polls question whether they will even reach three figures. The Liberal Democrats could climb from 11 at the 2019 election to 50. Reform UK, while projected to win as much as a 16% share of the vote, are unlikely to win more than two seats, but will cost Conservatives seats (to Labour and other parties) across the country.
