Ireland will be worst hit by a Brexit, according to the latest warning from European economists.
German think-tank, the Ifo Institute, says Ireland's trade links with the UK make us more vulnerable than our EU neighbours.
Their claim is based on a survey of international experts who were asked if their country would be affected by Britain's exit from the European Union.
Their responses, on a scale of zero to 100, found that Ireland has the gloomiest outlook.
Brexit is expected to have a minimal impact on North America and the Middle East.
