Arlene Foster says she has spoken to Boris Johnson today as the former foreign secretary was elected leader of the Conservative Party. The DUP leader said the two unionist parties would revisit the confidence and supply agreement between them at the end of the current parliamentary term. Mrs Foster also said that Boris Johnson "understands the Democratic Unionist Party", adding that "Theresa May and those around her didn't actually understand what made unionists tick in Northern Ireland".
