The Democratic Unionist Party is set to demand tax cuts costing £460million to keep Theresa May in power after Brexit in two years’ time, The Telegraph can disclose.

The party wants the money to pay for cuts in corporation tax, air passenger duty and VAT on hotels and restaurants in Northern Ireland as part of its price of continuing to prop up Mrs May’s minority Conservative government.

The cash demand will form part of the next bill for DUP MPs’ continued support of Mrs May’s Government when their “confidence and supply” agreement is reviewed after Britain leaves the European Union in March 2019.
