Tánaiste and Minister for Foreign Affairs Simon Coveney has said Ireland needs to prepare for the "worst possible outcome" on Brexit.
Mr Coveney said the British political system is "unpredictable and semi-chaotic at the moment".
He said with a "deeply divided" parliament Ireland cannot be sure what the outcome of the votes there will be this week.
Mr Coveney said a no-deal Brexit has shifted from a "remote possibility" to a "real possibility", but said while he personally does not think it will happen, we cannot be sure.
He said the Government continues to work with other EU countries and the UK to find a way forward.

But over the next ten days Ireland needs to focus on getting ready for a no-deal Brexit "just in case", adding there are many businesses in Ireland that are not as prepared as they should be.
He said there is support, advice and funding available, but at a minimum, companies should be registering with Revenue to make sure they understand what is required in terms of customs checks and potentially, the imposition of tariffs.
