In UK, the Supreme Court will begin a landmark hearing today into whether Parliament's consent is required before official Brexit negotiations can begin. The apex Court's 11 justices will hear a Government appeal against last month's High Court ruling that only Parliament has the authority to trigger Article 50. <br/><br/>Meanwhile, Prime Minister, Theresa May, has said that she intends to officially notify the rest of the EU of the UK's intention to leave, beginning two years of talks over the terms of separation by the end of March by invoking Article 50. The powers traditionally held by the monarch but now used by politicians to enable decisions about joining or leaving international treaties to be made without a Parliamentary vote. Britain voted to leave the EU, by a margin of 51.9% to 48.1%, in a referendum in June.
