Speaking after the result was called, the new MP for Belfast North spoke of his pride in the constituency.
He said: "North Belfast... is the easily the best part of Belfast. I was born there, I raised my kids there, I live there now.
"I'm very, very proud to be from North Belfast and I think that this election is about the future of North Belfast.
"We saw the threat of Brexit and what that meant for the people of Belfast, we saw the threat to the economy, the threat to our children's futures and I think that message, that remain voice that was heard in 2016, was amplified beyond recognition again tonight."
The turnout for Belfast North was 68.43%.
