Foyle is essentially the city of Derry. The Nationalist parties got four seats with 58.5% of the vote last time, boosted by independents who were mostly from a similar part of the spectrum; Unionists got one with 18.5%, and the People Before Profit Alliance broke through to take the last seat with 10.5%.

Five of the six incumbents are standing again, with SF’s Martin McGuinness retiring. The SDLP and SF are defending two seats each with 1.8 and 1.7 quotas respectively; the DUP and PBPA are defending their seats with 0.7 and 0.6 of a quota each. In 2016 there were 1.1 Unionist quotas (counting the votes of a former DUP independent) and 3.5 quotas for the Nationalist parties (not counting the independents, or PBPA who do not designate as Nationalists in the Assembly).

The DUP seat therefore looks pretty safe; on paper, the SDLP and SF should be able to divide the other four evenly between them, shutting out the PBPA. But it will take good balancing and there is little room for manoeuvre. If Eamonn McCann does hold his seat, SF are more likely than the SDLP to lose out, having (slightly) fewer numbers to start with, with their best-known figure no longer on the scene, and being less likely than the SDLP to benefit from transfers from other parties.
