Hello and welcome to the third in our series of Red Lines' constituency profiles with just three weeks to go until election day.

This week we're looking at three more potentially intriguing electoral battles in Lagan Valley, Upper Ban and Nurean Armagh.

And with me to talk our way through the personalities, the all-important local issues and the possible impact of recent boundary changes are our resident numbersman, Dr David McCann, the Belfast Telegraphs political editor Suzanne Breen and our very own political correspondent, Gareth Gordon. Welcome to everyone. David, let's dive in with one of the most fascinating constituencies in this election. Give us your Lagan Valley at a glance.

Okay, so Lagen Valley is the DEP's third most marginal seat in Northern Ireland has been in the hands of the DEP since Geoffrey Donaldson,

defected over to the party in 2004. At the last election, he was re-elected with a majority of 6.5,000 votes,

which was actually one of his smaller and tighter wins.

In 2019, there was a 16.4 percentage point swing away from the DEP. That was the biggest drop

for the DUP across Northern Ireland in 2019. 2019 Conversely also saw Alliance score their best ever result in the constituency.

Sorsia Eastwood polled a very credible 29% of the vote.

Another thing about 2019 that I think is worth noting, the combined unionist vote, so this is the combination of all the unionist candidates, came in at just under 65%.

And that was the lowest in the entire history of the constituency since it was created in 1983.

Jonathan Buckley steps up for the DUP.

He's coming in from Upper Ban, standing for the first time in the constituency.

You also have the EUP's deputy leader, Robbie Butler.

He also stood in 2019.

He took just under 20% of the vote in the constituency.

Sinn Féin are not standing a candidate here.

The SDLP are running side Lee as well.

The TV are also running Lorna Smith.

And that could be critical because, of course,

one of the things that Alliance,

is Sorsia Eastwood will be looking at is a potential split unit's foot
