From a peak of 396-402 the Tories’ Election Seats spread has fallen to 365-371 on the eve of the vote, with controversies surrounding the ‘dementia’ tax and police funding damaging the standing of Theresa May’s party.

Labour have, obviously, been the main beneficiary of this shift, climbing to 198-204 from 157-163 three weeks ago. However, if accurate, that would still leave Corbyn on track to lose around 30 of the seats won by the Miliband campaign back in 2015.

According to the behaviour of Spreadex’s clients, the Tories can expect to win anywhere between 360 to 380 seats come Friday morning. When the party’s Election Seats spread has been above 380 people have tended to sell; at its current 365-371 price, however, there has been far more positive interest in the incumbent Prime Minister. As for Labour, there is marginally more money buying Corbyn and co. than selling. They have found most of their Election Seats support around the 170 mark, with more sellers creeping in as the spread crossed 200.

While Tim Farron has failed to engender much public support – despite billing the Lib Dems as the anti-Brexit party – the former coalition partners have drawn most of the spread betting interest. Though there is a decent chunk of change buying Liberal seats (which currently sits at 10.5-12.5), the most significant stakes have backed the further erosion of the party’s parliamentary power.

Elsewhere perhaps the most noticeable move spread-wise is the No Overall Majority Binary. A few weeks ago it was at 2.9-5.3, with the Overall Majority spread at a near certain 90-98.1. Since then a bit of doubt surrounding the Tories’ ability to produce a landslide victory has caused the No Overall Majority spread to rise to 11.1-18.2, with a swell of buyers since the start of June.

Finally there is the Registered Voter Turnout Percentage spread, which stands at 63.5-64.5. That would put the turnout at lower than both the 2015 election, where it was 66.4%, and the Brexit referendum, which reached 72.2%. Given that Labour’s chances of avoiding a hammering are based on the under-30s coming out in droves, those numbers don’t look promising for Jezza.
