The SDLP's council elections performance shows that its "renewal project" is "working very well", says Colum Eastwood.
The SDLP leader says he's "very, very happy" with how his party's candidates have done after they made gains on Derry City and Strabane District Council.
With two SDLP candidates as the first councillors to be elected in Derry City and Strabane, the SDLP vote will be seen as the party beginning to reverse its downward spiral.

MP Mark Durkan lost his Westminster seat to Sinn Fein in 2017.
SDLP leader Colum Eastwood was in a buoyant mood as the declarations were made.
SDLP leader Colum Eastwood has said he does not feel betrayed by former party leader Mark Durkan's decision to run in the European election for Fine Gael.
