As the United States, or those that voted for him, prepared to say Hail to the New Chief at the inauguration today, an equally divisive issue got another airing this side of the Atlantic this week - Brexit. British prime minister Theresa May confirmed the UK would not remain a member of the EU trade bloc's single market but would seek access to it through a free trade agreement which she said could see the automotive sector trading using single market "arrangements." In a speech outlining 12 aspects of the intensely complex mechanism by which Britain would exit the European Union (EU), May also warned those opposed to the UK quitting the union: "This is not a game." London did want some form of customs agreement, however.
