The document codifies the framework for the direct implementation of London's Brexit agreement with Brussels.
The BBC quoted the British government as saying that they are seeking to avoid a "black hole in our statute book" and disruptions to the business sector and individuals amid the UK's withdrawal from the EU.
According to Brexit Secretary David Davis, Britain's withdrawal is scheduled for March 29, 2019 irrespective of whether British MPs support or reject the bill in a take-it-or leave-it vote.
In a British referendum on June 23, 2016, about 51.9 percent of voters said "yes" to their country leaving the EU.
London's Brexit talks with Brussels kicked off on June 19, 2017. The negotiations, held in week-long rounds on a monthly basis, are set to wrap up by late March 2019.
