Colum Eastwood arrives in Magherafelt.

Sources in the Meadowbank Sports Arena have indicated Mr. Eastwood has outpolled the outgoing MP, Elisha McCallion of Sinn Féin by a 'margin.'

Mrs. McCallion won the seat with a majority of 169 over former SDLP leader Mark Durkan in 2017 but it's believed that was reversed on Thursday.

Mr. Eastwood arrived at the Meadowbank Sports Arena at approximately 1.30 a.m.

Colum Eastwood is expected to gain a seat for the SDLP in Foyle.
