Uncertainties remain for UK as Brexit process begins

On Wednesday, the United Kingdom formally launched the process for it to leave the European Union, with Prime Minister Theresa May triggering Article 50 of the Lisbon Treaty, which opens a two-year window for negotiations on it leaving the bloc.

Though May has promised to "make a success" of the divorce, there are many uncertainties and restraints that are likely to undermine her efforts to achieve that goal.

Internally, she is facing a highly disunited nation, especially as Scotland, in a bid to hold on to EU membership, is seeking a new referendum on independence.
