From Article 50 to Phil Collins on stage: What we can expect from 2017
Here we look forward to some of the events already earmarked for 2017:
The New Year is anticipated to start with a bang as the Supreme Court hands down its Brexit decision. The 11 justices will rule on whether Prime Minister Theresa May has the legal power to use the royal prerogative to trigger Article 50 of the Lisbon Treaty and start the two-year process of withdrawing from the European Union, or, as opponents claim, an act of parliament is needed.
It may once have seemed impossible, but Donald Trump's inauguration as 45th president of the United States will take place in Washington on January 20

March 24 will mark one year since co-pilot Andreas Lubitz locked Germanwings Flight 9525's captain out of the cockpit and deliberately set the plane on a collision course with an Alpine mountainside. All 150 people aboard, including Lubitz, were killed in the crash.
March 31 is the deadline for Brexit Day - MPs voted in December in favour of the Government's timetable to trigger Article 50 by this day and begin withdrawal from the European Union. The symbolic motion, which was non-binding, was approved by 448 votes to 75, majority 373.
The first round of the French presidential election will be held on April 23. Former prime minister Francois Fillon will be the Republican party's candidate, standing against the far-right Front National's Marine Le Pen and a field including an as-yet unchosen socialist candidate. If no candidate wins an outright majority, the top two will go head-to-head in a second vote on May 7.
Voters will head to the polls on May 4 for local elections in England, Wales and Scotland which will be seen as a key test, post EU referendum, for both Prime Minister Theresa May and Labour leader Jeremy Corbyn.

August will mark 20 years since the tragic death of Diana, Princess of Wales. The mother of the Duke of Cambridge and Prince Harry was just 36 when she and boyfriend Dodi Fayed died in Paris in the early hours of August 31 1997. In celebration of her life, Kensington Palace, which was her home from 1981, will host a new exhibition and a commemorative garden open to the public.
