Britain is due to pull out of the EU in less than three weeks, on March 29, but Prime Minister Theresa May's government has not been able to win parliamentary approval for its agreement. The impasse has raised fears of a chaotic "no-deal" Brexit that could disrupt businesses in Britain and the 27 remaining EU countries.
