Martin says 'Europe needs to develop a stronger self-reliance' amid Trump's Greenland threats

Taoiseach Micheál Martin said it had been a 'difficult' week for EU-US relations

Taoiseach Micheál Martin said he was 'optimistic' about the future of both Europe as a project and of the Irish-American relationship.

Donald Trump's aim of taking over Greenland shows the EU must be more self-reliant, the Taoiseach has said.

Micheál Martin was speaking at the World Economic Forum in Davos where he said it had been a "difficult" week for EU-US relations as Mr Trump ramped up his rhetoric around US control of the Arctic island, which is under Danish control.
