Will there be an election upset on Thursday?

Tomorrow, voters will head to the polling booth to cast their vote in the 2024 general election. Will there be any surprises in store? So far, there has been little movement when it comes to the gap in vote share between Labour and the Tories. However, there's still plenty of uncertainty across the parties as to what the exit poll will say at 10 p.m. on Thursday night.  James Heale speaks to Katy Balls and James Kanagasooriam, chief research officer at Focaldata.
