As Chancellor Rachel Reeves prepares to deliver the Budget, here's what the our poll tracker tells us about the state of the parties.
Polling suggests that on average less than a fifth of voters would back either Labour or the Conservatives were a general election to be held tomorrow.
Reform UK's average among five different companies for the two weeks up to 24 November was 29%, down a few points from its peak of 32% in October but still clearly ahead of everyone else.
The Greens and Liberal Democrats are currently neck and neck on an average of 13%, but the figures differ between polling companies.
We only include the headline percentages on voting intention, which pollsters calculate by excluding or otherwise adjusting for those people who answered "don't know" or "won't vote".
And these polls are conducted across the whole of Great Britain, so the Scottish National Party and Plaid Cymru's figures are low because they only stand in Scotland and Wales respectively.
You can see the averages in the lines in the chart below while the dots show the positions of each party in individual polls.
