May warned not to rely on DUP votes if Brexit deal treats Northern Ireland differently

The UK Government will not be able to rely on the votes of the DUP in parliament for any Brexit deal that treats Northern Ireland differently from the rest of the UK, one of the party's MPs has warned.
Sammy Wilson's warning came amid pressure from the Irish Government for the UK to agree a special arrangement under which Northern Ireland would continue to observe the rules of the EU's customs union to avoid a hard border with the Republic.
