A sophisticated new poll has suggested that the Conservatives would lose all their Norfolk seats except one, if an election were held today.

The survey of 10,000 people, commissioned by the Trades Union Congress (TUC) and carried out by the pollster Opinium, has found that prime minister Liz Truss, in her South West Norfolk constituency, would be the party's sole survivor in the region, while Labour and the Liberal Democrats would sweep the rest of the board.

Across Britain, it shows a 1997-style landslide for Labour, who would win 411 seats.

The Tories - who have plunged in the polls since Ms Truss' government outlined its controversial mini-budget last month - would only secure 137 seats, with the Lib Dems up at 39 and the SNP down at 37.

The projected results were produced using a method called multi-level regression and post-stratification (MRP).

It works by taking a national poll result and mapping that result onto different constituencies, using advanced data about the demography of each of those seats.

MRP polling conducted in the days ahead of the 2019 general election was only off by about 30 seats.

In Norfolk, it showed the following results:
