The Tánaiste Simon Coveney says plans for a no-deal Brexit are a "sobering read".

The Government published details of their disaster planning on Wednesday night.

This 131-page document is the first real look at what a no-deal Brexit might look like for Ireland.

On the infrastructure side, Dublin and Rosslare Ports will need an upgrade to deal with a significant increase in customs checks - and to house at least 200 extra Revenue staff.

That will also need to be done at airports.

Emergency legislation will be needed to do a host of things - including keep planes travelling in and out of the UK in the air.

There are 45 emergency legislative changes outlined.

There will also be big changes for importers and exporters: the deal warns of long delays for businesses who use the UK as a landbridge for goods.

Work is underway to ensure there will not be food or medicine shortages as a result.

The agri-food sector is also to expect a significant hit.

The document is light on how fishing will be safeguarded.

And there is also no contingency plan for avoiding border infrastructure with the North - but there is a commitment to work to avoid it.

Sources admitted there are some areas that cannot be planned for, as no one knows what is going to happen.

The document will be updated again in January, as the political stalemate in the UK makes a no-deal scenario look ever more likely.

Mr Coveney said the report paints a start picture.

"It's a sobering read, and I think it reminds people that there is no such thing as a contingency plan which will just maintain the status quo as we enjoy it today - no matter what we do.

"But there are things and actions that we are taking to ensure that we protect, as best we can, Ireland and its economy".

It comes after the European Commission published its latest plans to prepare for a no-deal scenario, with 14 temporary measures.
