BRUSSELS (Reuters) - The European Union's chief Brexit negotiator Michel Barnier warned British ministers and businesses who are calling for "frictionless trade" with the EU after Britain leaves that that is "not possible".
Addressing an EU business forum in Brussels on Thursday, Barnier said London's "red lines" for a future trade relationship meant Britain was definitely leaving the single market and the customs union, and only membership of both allowed "frictionless" trading arrangements.
But Britain will stick by its aim to get a comprehensive free trade deal and customs agreement with the EU to ensure that trade is "as frictionless as possible" once it has left the bloc, a spokesman for Prime Minister Theresa May said.
Barnier said, according to remarks prepared for delivery, that he was unsure the EU's refusal to grant single market access piecemeal and insistence on control of standards in the single market "have been fully understood across the Channel".
"I have heard some people in the UK argue that one can leave the single market and keep all of its benefits - that is not possible," he said. "I have heard some people in the UK argue that one can leave the single market and build a customs union to achieve 'frictionless trade' - that is not possible."

Stressing that time was tight for a deal by the time Britain automatically leaves the bloc on March 30, 2019 - "time flies", he said. Barnier said he was ready to handle a failure of talks and "no deal" but that would be damaging, especially to Britain, and he saw "no reasonable justification" for it.
"A fair deal is far better than no deal," he said, turning around a phrase popularised by May that no deal is better than a bad deal.
He called for rapid agreement on priority issues in talks begun last month to build a "climate of trust" so that trade negotiations could begin as soon as possible. But in urging businesses to prepare for Brexit now, he stressed that whatever deal was done would carry "significant consequences".
"A trading relationship with a country that does not belong to the European Union obviously involves friction," Barnier said. He cited disruption to cross-border traders processing value-added tax (VAT) and a need for all EU imports of animals and animal products to be tested at borders.
Those issues are of particular concern in Ireland, where farming businesses on either side of the new UK-EU border on the island fear disruption. Barnier repeated EU willingness to make a priority of agreeing border issues on Ireland, where leaders on all sides fear a "hard" frontier could also undermine the fragile peace in the British province of Northern Ireland.
After Japan and the EU agreed a free trade pact, Irish farm commissioner, Phil Hogan, said the deal "shows the importance of size in global trade negotiations".
"A strong, unified European Union, representing 500 million citizens, can deliver benefits for both our exporters and our citizens. No individual member state could ever hope to achieve what the EU can achieve together," he said.
