Minority government probabilities assume possible alliances between the Conservative and Reform parties, and between Labour, Liberal Democrats, SNP and Plaid Cymru.

Commentary for end-March 2025

Posted 1 April 2025

This month, Reform have lost a little ground to Labour, possibly after the spat which saw the suspension of MP Rupert Lowe. Labour is now 1pc ahead of Reform, with the Conservatives only one point further behind.

In terms of seats, we calculate that the three big parties would be fairly equal, but Labour would (just) be the largest party. However, a Reform-Conservative coalition could be the most likely option in practice, albeit with a minimal majority.

But the situation is very fluid, and small swings will have big effects. Don't underestimate the power of a single percentage point. Parties can gain or lose around 30 seats just for a 1pc swing up or down. For example, if Reform gained 2pc more support from Labour they would gain another 56 seats.

Also, Richard Rose writes this month that Labour is Haemorrhaging Seats to Reform.
