What's behind the bounce back for the global GDP? Plus, what does the snap UK election mean for its economy?

The outlook for global GDP has started to look a whole lot sunnier. The International Monetary Fund (IMF) says the world's economy is on track for its strongest growth in half a decade. The IMF's prediction is that world GDP will hit a 3.5 percent increase in 2017 - that's a significant 0.4 percent rise from the original prediction of 3.1 percent for the year.

Further positive predictions for Europe's largest economies including the UK, with a two percent increase for the UK, demonstrating that Brexit has not affected the economic outlook there yet.

The forecast isn't just about the world's richest nations either, with emerging and low-income economies all seeing a more optimistic outlook. But there are still plenty of hurdles to clear.

The IMF's forecast also contained a warning about what could stall economic growth. This included political pressure to restrict trade and geopolitical tensions that could further hinder economic expansion.

Maurice Obstfeld, the Chief Economist at the IMF tells Counting the Cost about what's driving the recovery of the global economy and what could halt the favourable outlook.
