Some checks on goods and live animals may need to take place “near” the Irish border in a no-deal Brexit, Taoiseach Leo Varadkar has said.
In a speech to business leaders in Dublin, Mr Varadkar said that “as far as possible” they will take place at ports, airports and firms.
The Irish prime minister said his government was “working out the details” with the European Commission.
He also said there was “a significant and growing risk of no-deal”.
Speaking at a British-Irish Chamber of Commerce dinner, Mr Varadkar said he would continue efforts to avoid a no-deal, but would not do so “at any cost”.
“I do fear it, but I am prepared for it” he said.
