SOFIA (Reuters) - British Prime Minister Theresa May denied on Thursday she was “climbing down” on plans to leave the EU customs union.

Asked about reports that her government would ask Brussels to stay in the European Union’s customs area beyond the end of a post-Brexit transition period in 2020, she told reporters at an EU summit in Bulgaria:

“No. The United Kingdom will be leaving the customs union as we’re leaving the European Union. Of course, we will be negotiating future customs arrangements with the European Union and I’ve set three objectives ... in those.”

She said these were that Britain should have its own trade policy with the rest of the world, should have frictionless trade with the EU and that there be no “hard border” with Ireland.
