In the border constituency of Newry and Armagh, fears of a hard border following Brexit remain a key worry for many voters.
Sinn Fein’s Mickey Brady won his Westminster seat in 2015 with 20,488 votes by a comfortable margin of just over 4,000 votes of the UUP’s Danny Kennedy.
In the march Assembly elections for Newry and Armagh, Mr Kennedy lost his seat following a bruising day at the polls for his party.
With his high profile in the area, it could have been assumed he was the natural candidate to stand for Westminster in June.
But speaking shortly after his recent defeat he indicated it was unlikely he would be returning to elected politics.
Suggestions that Mr Kennedy would be parachuted in as a candidate for Upper Bann also never materialised.
The DUP will now stand William Irwin, after the DUP leader Arlene Foster and UUP leader Robin Swann could not agree over an electoral pact for Newry and Armagh.
Mr Irwin topped the poll at the Assembly election and was the sole Unionist to keep his seat.
The UUP are now standing councillor and architect Sam Nicholson.
Although not as well-known as the other established candidates, he is hoping to follow in his father’s footsteps to Westminster.
Jim Nicholson was MP for the area between 1983-84 before later being elected to the European parliament.
The SDLP are contesting candidates in all 18 constituencies, with MLA Justin McNulty standing in Newry and Armagh.
The former GAA all Ireland winner finished third overall in the March assembly election, something he called a great day for nationalism.
Going by the results in 2015 it seems unlikely he will have enough of a vote share to finish ahead of Sinn Fein, but after his March election he insisted that like his sporting days, in politics he thrives on a challenge.
The Alliance candidate is Jackie Coade who has the gargantuan task of making an impact in one of Sinn Fein’s most secure seats.
