Future of the financial sector in the UK and the decline of the EU

So there are a lot of stories being thrown around about how the financial sector in the UK will loose the right to serve the EU.
All this depends on if there is a hard or soft Brexit.
How likely is it that the financial sector will relocate out of London?

There is a trend all across Europe where all the right wing parties are gaining massive popularity. Most recently in Germany where the anti immigration party,afd, is gaining massive popularity just in time for the national elections to be held next year. The party of the chancellor, the CDU party , suffered it's biggest lose in recent times.

Could we see Germany leaving the EU?

Could we see other European countries leave the EU in the near future?

My prediction is that the afd gets third place in the German elections next year. Because of this recent rise of the afd, I can see there being a referendum promised in Germany next year or the year after.
