LONDON Interior minister Amber Rudd said on Sunday the British government did not yet know what kind of cost there may be for trying to get the "widest possible access" to the European Union's single market.
Prime Minister Theresa May will trigger Article 50 of the EU's Lisbon Treaty on Wednesday, hoping to secure what she calls a "good deal" of close cooperation on the economy and security while being able to control immigration.
"I certainly do think that we should try to have the widest possible access to the single market ... we don't know what that cost would be, we don't know that at all, that is going to be part of the negotiations," Rudd told the BBC's Andrew Marr show.
"We have a lot to offer in this negotiation as well so we must not ever forget that it is going to be two-way."
