The data also found that Leicestershire also leans toward Reform (albeit with only a small lead) due to a collapse in the Conservative vote, leaving Labour in a possible second place.
Overall, Reform UK is getting its highest share of the vote in the North East, East Midlands, and East of England.
Kelly Beaver, chief executive of Ipsos UK and Ireland said: “This data, in line with most of the evidence that we have seen both in the run-up to this election and since the campaign started, in terms of the mood of the nation and real election results in local elections and byelections, suggests that the British political scene could be heading for yet another significant shift.”
