Sedgefield was Tony Blair’s constituency for nearly 25 years.
It used to be one of the safest Labour seats in the country.
Now it is a Conservative target, which would change hands on a swing of 7.3% – the sort of swing that would deliver Boris Johnson a very comfortable majority in the House of Commons.
He visited the area on Wednesday as part of a tour of Tory targets in north-east England.
This part of the country could be fertile ground for the Conservatives at the election.
On a 7.3% swing, four Labour seats would fall to the Tories – including Sedgefield.
He has held the seat continuously since 2007 and has built up a loyal local following.
In 2017, he had a majority of 6,059 and won over half (53%) of the vote.
At this election, he is up against candidates from the Conservatives, Liberal Democrats, Greens and Brexit Party, plus an Independent.
With such a variety of opponents, the anti-Labour vote could end up split – and possibly increase the chances of a victory for Mr Wilson.
