In a clear swipe at Westminster, Mr Macron warned: "If the United Kingdom isn't capable - nearly three years after the referendum - of putting forward a solution that gets a majority, it will have decided itself, de facto, to leave without a deal, and we can't avoid that failure in place of the United Kingdom". "Though it remains to be seen if sub-contracting out the future of Brexit to Jeremy Corbyn, someone whom the Conservatives have demonised for four years, will end happily", it added.
"The EU can not be held hostage on a long-term basis to the resolution of a political crisis in the United Kingdom", he said.
Simon Coveney said Ireland had intensified its no-deal contingency planning with the EU Commission but checks at EU ports on Irish products were not a runner.
The French President has insisted that the European Union won't abandon Ireland, no matter what happens with Brexit.

A fresh battle between the United Kingdom and Ireland is looming after Mr Varadkar insisted a border down the Irish Sea is back on the table.
Mr Varadkar said Ireland must protect the single market because "it's in our interest".
She voted for another referendum and to revoke article 50, but against a customs union or single market arrangement.
"The UK is being consumed by Brexit, but Ireland and France and the European Union shouldn't be consumed by Brexit, we have a positive agenda for the EU which we want to deliver", he said.
Irish Premier Leo Varadkar travelled to Paris to meet with Emmanuel Macron, where he thanked France for its ongoing solidarity with Ireland in the hard Brexit period.
In a hastily arranged statement from Downing Street, she said she was seeking another short extension to Brexit.
He added: "I think we need to be open to any proposals that she may bring forward to us".
