A party needs 21 of the 40 seats to outvote the rest. No party has that: Sinn Féin is largest with 18. Northern Ireland’s councils share out the chair, deputy chair and committee chairs among the parties in proportion to their seats, so the council is run by several parties together. SDLP is second with 10 seats, from 15 candidates.

One council, and Stormont for the rest
Castlederg has no county council and no town or parish council: since 2015 Northern Ireland has had 11 councils, each the only council for its area.
Bins and recycling, leisure centres, parks and cemeteries, local planning, building control, environmental health, licensing, tourism and local economic development, and the community plan.

Who to ask
Green: the council. Gold: a Stormont department or one of its agencies. Gray: another public body. The police district shares the council’s boundary, so Derry City and Strabane’s Policing and Community Safety Partnership covers the same ground as the council.

Each district electoral area elects five to seven councillors by single transferable vote: voters number the candidates in order, and a candidate who reaches the quota is elected, with spare votes passed on to the next preference. An area can reach beyond the town. A councillor who stands down is replaced by their party (co-option), so the names can change without an election.
