London, Dhu-AlHijjah 28, 1437, September 29, 2016, SPA -- Prime Minister Theresa May's failure to give detailed plans for her Brexit negotiating strategy and timetable is confusing for other EU nations and unsettling for businesses operating in Britain, a think-tank said on Thursday, according to dpa. There has been "a gaping void of information" about how the government plans to move forward following June's vote for Britain to leave the European Union, the Institute for Government said in a report. "The prime minister's silence about how she intends to reach an initial negotiating position is proving problematic," the think-tank said, urging her government to "move swiftly to spell out its plan." Civil servants are "building the machinery to respond to Brexit, [but] politicians don't yet know what to do with it - or if they do, they aren't saying," it said, adding that "valuable time and energy is being wasted on political squabbles and turf wars." Planning for Brexit could cost the government some 65 million pounds (85 million dollars) annually and require hiring an extra 500 civil servants, said the London-based think-tank, which focuses on improving the effectiveness of government. "Silence is not a strategy," said Hannah White, co-author of the report. "The current situation - where we are left to interpret personal musings of individual ministers - is frustrating those looking for an early exit, perplexing those with whom we have to negotiate and unsettling those looking to do business in the UK," White said. --SPA 03:30 LOCAL TIME 00:30 GMT www.spa.gov.sa/w
