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.
Victory here would have enormous symbolic value for the Conservatives, thanks to its associations with Mr Blair.
But Labour’s Phil Wilson will not make it easy for them.
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.
Why are you making commenting on The National only available to subscribers?
We know there are thousands of National readers who want to debate, argue and go back and forth in the comments section of our stories. We’ve got the most informed readers in Scotland, asking each other the big questions about the future of our country.
Unfortunately, though, these important debates are being spoiled by a vocal minority of trolls who aren’t really interested in the issues, try to derail the conversations, register under fake names, and post vile abuse.
So that’s why we’ve decided to make the ability to comment only available to our paying subscribers. That way, all the trolls who post abuse on our website will have to pay if they want to join the debate – and risk a permanent ban from the account that they subscribe with.
The conversation will go back to what it should be about – people who care passionately about the issues, but disagree constructively on what we should do about them. Let’s get that debate started!
Callum Baird, Editor of The National
