LONDON: With Britain just 12 weeks away from the day it is meant to leave the European Union, one thing is becoming clear — uncertainty over what Brexit will mean is hurting the economy. A raft of economic figures released Friday showed the British economy weakening at the turn of the year just as Prime Minister Theresa May delayed a parliamentary vote on the Brexit deal she agreed on with the EU. House prices are down and business optimism in the key services sector is at its second-weakest level since the global financial crisis a decade ago. One of Britain’s leading mortgage providers said house prices fell in December by their biggest amount in six and a half years. The Nationwide Building Society said that house prices, a barometer of the health of the wider economy, fell by a monthly rate of 0.7 percent, the biggest monthly decline since July 2012. On an annual basis, prices were up only 0.5 percent, the lowest since February 2013. “It is likely that the recent slowdown is attributable to the impact of the uncertain economic outlook on buyer sentiment, given that it has occurred against a backdrop of solid employment growth, stronger wage growth and continued low borrowing costs,” said Robert Gardner, Nationwide’s chief economist. The big uncertainty surrounding the British economy relates to Brexit, which is officially due to take place on March 29. May delayed the vote on her deal to the middle of this month after realizing she was heading for a big defeat. As things stand, it looks like her deal, which foresees relatively close ties between Britain and the EU in the trade of goods, will struggle to win enough support. What would happen then is unclear. Some lawmakers back another Brexit referendum while others think the country would be fine crashing out of the EU after some initial turbulence. Given the uncertain outcome of the vote in Parliament, both the EU and Britain are preparing for a possible “no-deal” Brexit. The British government, for example, is stockpiling pharmaceuticals and has bought a number of super-sized fridges to keep them viable. The Bank of England, which warned in November that a “no-deal” Brexit could see the British economy contract by a whopping 8 percent within a few months, also published figures showing a further slowdown at the end of 2018. It found mortgage approvals for house purchases fell significantly in November to a seven-month low and that year-on-year unsecured consumer credit growth slowed during the month to the lowest level since March 2015.
