Rishi Sunak's Suffolk visit was one of only five he has made to dozens of constituencies where cabinet members and other prominent Tory politicians are at risk of losing their seats, according to an analysis of his campaign route.

The Prime Minister visited Sizewell in the Suffolk Coastal constituency on June 19, where polls predict Tory candidate Therese Coffey is expected to lose with a margin of 5.5 points behind first place.

Only four other visits around the country, including one to his own Richmond and Northallerton constituency, have been to the 45 seats considered to be at risk for the Conservatives, as of Friday.

The data on which seats are at risk is based on polling and analysis of 22,149 people by Survation between May 31 and June 13.

During the visit to the Sizewell B nuclear power station, Mr Sunak praised Dr Coffey, who has served as the constituency's MP since 2010, calling her a "dear friend of mine".

He also pledged to review plans to route new energy infrastructure, including pylons and cables, through the Suffolk countryside, saying: "Some of the needs we are using to make these decisions are a decade old now".

However, campaigner Fiona Gilmore, from Suffolk Energy Action Solutions, said: "Sunak could have done a U-turn as he did on HS2, but this one would have been a turn towards the future, not past technology, a turn towards a smarter solution, a win-win for everyone."

The Suffolk Coastal seat has been solid Conservative territory since 1951, with Dr Coffey having a majority of over 20,000 in 2019.

As well as Dr Coffey, the candidates include Julian Cusack (Green), Julia Ewart (Lib Dem), Matthew Jackson (Reform UK) and Jenny Riddell-Carpenter (Labour).
