"This bill is essential for preparing the country for the historic milestone of withdrawing from the European Union," Brexit Secretary David Davis told MPs ahead of the vote. "It ensures that on day one, we'll have a statue book that works, delivering a smooth and orderly exit desired by people, businesses across the United Kingdom and being delivered by this government."
However, the unelected upper House of Lords may insist on further changes when peers begin their scrutiny on January 30, while ministers still face opposition from the devolved Scottish and Welsh administrations. The bill is only one of several that Prime Minister Theresa May's minority government must pass to prepare Britain for its withdrawal from the EU in March 2019.
'Big battles' ahead MPs had tabled more than 500 amendments and spent more than 80 hours in debate, and Davis said the legislation was heading to the Lords in an "improved" state. But Keir Starmer, Brexit spokesman for the main opposition Labour party, said ministers ignored its concerns and the bill was "still not fit for purpose". The draft legislation passed by 324 votes to 295.
