The world is reeling from one of the most genuinely stunning developments in political history.

Donald Trump will be the next President of the USA. The Commander-in-Chief. The man with the nuclear codes.

As for what happens next, well... who knows. But here are some educated guesses.

The short-term bad news...

There will be financial instability. As a Trump victory became more likely, the New York stock exchange plummeted. The dollar may well fall, and companies will look at Trump's general opposition to foreign trade and assess what this means for their futures.

The short-term good news...

Barack Obama is still the president. Trump will be inaugurated on January 20. Work is under way in Washington, DC to prepare for the ceremony on the steps of the Capitol Building.

What happens now after the Brexit High Court ruling?

The first week - dismantling the Obama era

Because Barack Obama was a Democratic president with a Republican House of Congress and Senate, he was forced to issue what are called executive orders just to get anything done.

The bad thing about this is they can be reversed by a successor - particularly one who opposes pretty much everything you've done.

One of Trump's top priorities will be taking apart the Affordable Care Act - dubbed Obamacare by Republicans - which extended healthcare cover to millions.

He'll probably also look to withdraw from the Paris climate change agreement. So if you're keen on having an inhabitable planet in future, and on people getting treated when they're ill, this isn't great news.

The end of the West

The USA's closest foreign ally won't be the EU or UK - the special relationship will basically extend to giving Nigel Farage a job in Washington.

Vladimir Putin, seemingly intent on exerting control over countries which gained their independence from the Soviet Union after the Cold War ended, will be Trump's best friend abroad.

The president-elect has already suggested he may not defend a NATO ally which came under attack. Indeed, the whole future of the organisation created in the wake of World War II is now in question.

Will he build the wall?

One of the most controversial aspects of the Trump campaign was the pledge to build a wall - paid for by Mexico - on the border.

Let's call this now - it won't happen. Most Trump supporters were happy to chant "build the wall", but in reality they know it's a non-starter.

The French election is coming up...

The far-right Front National in France has made significant progress in France under the leadership of Marine Le Pen.

Her campaign for the French presidency next spring could be boosted by the Trump effect - and France could be on its way out of the EU. In fact, it could mean the beginning of the end of the EU.

But this could work the other way - if Le Pen can be tied to Trump by her opponents, the centre-right in particular could make gains.
