The minister said the decision to fix the exit time in law was made after listening to the public and lawmakers in order to "remove any confusion or concern about what 'exit day' means."
"Our amendment makes it crystal clear that the UK is leaving the EU at 11 p.m. on March 29, 2019," Davis said, as quoted by the national broadcaster BBC.
In an article for the Daily Telegraph newspaper, UK Prime Minister Theresa May warned lawmakers against attempts to slow down or stop the exit process as the bill travels through parliament over the next month.
In a British referendum on June 23, 2016, about 51.9 percent of voters said "yes" to their country leaving the EU.
