The global economy is set to see its fastest pace of growth in six years despite a slowdown in the US and Brexit fears, according to think tank OECD.

The Organisation for Economic Cooperation and Development raised their growth expectation to 3.5 percent this year, its strongest estimate since 2011. Growth is then forecast to rise to 3.6 percent in 2018.

The latest figure represents an increase on the 3.3 percent estimate given in March, boosted by an improvement in trade and investment flows offsetting a weaker outlook in the US.

Forecasts for the UK’s growth remained the same, at 1.6 percent in 2017 and 1 percent in 2018. It added that growth in the UK was likely to slow heavily in the upcoming years, as uncertainty from Brexit negotiations begins to impact the economy.
