May talked to Scotland's First Minister Nicola Sturgeon and First Minister of Wales Carwyn Jones on Friday, following her landmark speech on the potential future trade relationship between the United Kingdom and the European Union.
"Alongside the five foundations that would underpin the future partnership, she [May] said we would seek customs arrangements that would lead to as frictionless trade as possible with our European neighbours, as well as ensure no hard border between Northern Ireland and Ireland," the spokesperson said, as quoted in the government's press release.
