Law firm Clifford Chance has said the Brexit court defeat for UK government "has thrown a considerable spanner into the government's works".

"The government did not want parliament to have a say in whether or when the Article 50 notice is given, but the court has said that prior parliamentary involvement is a constitutional requirement for the UK.

"Unless the Supreme Court overturns the Divisional Court's decision, the government has no choice but to go to parliament. That risks, at the least, delaying the UK's withdrawal from the EU, and the consequences could extend further than that," the firm says.

The pound's gains after the Brexit court defeat for the UK government today are "unlikely to extend for too long or to run too far" Swiss bank UBS has said in a research note.

"Despite the potential for delays in triggering Article 50 that today's High Court decision introduces, our base case is still that the direction of travel remains one towards the UK leaving the EU, and an accelerated one for that matter compared to the summer," said John Wraith and Lefteris Farmakis.

They added that it's too early to tell whether parliamentary oversight of the negotiation process would reduce the probability of a "hard exit".

Although the FTSE 100 finished down earlier, Laith Khalaf of Hargreaves Lansdown points out that shares in domestic companies did well:

"In a reversal of recent fortunes the domestic UK stocks had the upper hand on the UK stock market on Thursday... The High Court ruling will be seen as increasing the odds of a soft Brexit, and the reaction of domestic stock prices shows the market thinks that would be preferable for the UK economy."

Royal Bank of Scotland finished up around 6%, Dixon’s Carphone was up around 4% as is British Land, with Marks & Spencer rising more than 3%, the firm said.

Luxembourg is famous for many things - castles, cured meats, one of its national languages, Luxembourgish.

However, it will soon add another string to its bow, this time in the form of asteroids.

Luxembourg has announced it will invest $27.6m in Planetary Resources, an asteroid mining company that counts Google co-founder Larry Page as an investor. 

Although it is US-based, Planetary Resources will conduct research and development at a new facility in Luxembourg.

Planetary Resources is hoping to launch its first commercial asteroid prospecting mission by 2020. 

Vill Gleck!

That's Luxembourgish for good luck.
