While the British public has voted to leave the bloc, the majority of UK lawmakers have opposed Brexit and voted against the move.
"There has to be some [internal UK] legislation [to start the Brexit process], no doubt about that," David Davis said, adding that "there may well have to be at least parliamentary ratification under the relevant 2010 legislation — the so-called CRAG [the Constitutional Reform and Governance Act 2010] — but that's the absolute minimum I can see."
On June 23, the United Kingdom held a referendum to determine whether or not the country should leave the European Union. According to the final results, 51.9 percent of voters, or 17.4 million people, decided to support Brexit, while about 16.1 million opposed it.
Prime Minister Theresa May has repeatedly stated that despite many members of the ruling Conservative Party opposing the decision, the referendum results have to be respected, saying that there is no way back and "Brexit means Brexit."
