UK PM May says Britain faces momentous change as it leaves EU

Britain is facing a period of momentous change following its decision to leave the European Union and will need to forge a new role in the world, Prime Minister Theresa May told the World Economic Forum in Davos on Thursday. May, who has said Britain wants a "bold and ambitious" trade agreement with the EU when it leaves the bloc, said Britain would step up to a new leadership role as a strong advocate for business, free markets and free trade after Brexit.
