From https://www.bbc.com/news/articles/c3gg66pm8ylo.
"The constituency was previously held by UKIP after former Tory MP Douglas Carswell defected to the party and triggered a by-election, which he won.
More than 70% of voters in the constituency backed Brexit in the 2016 referendum – the fifth highest figure in the UK.
In 2017 Conservative Giles Watling unseated UKIP, gaining the seat with a majority of more than 15,000.
By 2019, with no UKIP or Brexit Party candidate standing, Mr Watling’s majority grew to 24,702. He is defending the seat again in July for the Tories."
I would say he has an excellent chance.
