The Department for International Development is to be scrapped and the Foreign Office handed direct control of the £14billion aid budget, Boris Johnson is expected to announce on Tuesday afternoon. The Prime Minister is expected to tell MPs that the plans will give the UK a single voice on the world stage after Brexit when he makes a statement in the House of Commons. The Telegraph understands that Dominic Raab, the Foreign Secretary, will take direct control of the aid budget and be instructed to ensure that its spending is in line with UK foreign policy. The merger comes after Mr Johnson’s reshuffle four months ago which left seven out of the eight Dfid ministers with parallel jobs in the Foreign Office. The Telegraph first reported the likely merger in February.
