The vote on the Brexit plan of the current UK government is scheduled for Tuesday January 15.
Recent articles in the The Economist surprised me with the breadth of changes that will need to be accomplished when Britain exits the EU. Essentially all trade and other treaties negotiated by the EU while Britain was a member will need to be renegotiated by Britain. This leaves open the possibility of major disruption.
The consensus effects on the UK economy is a 3% drop in GDP versus remaining in the EU over the next few years if the soft Brexit plan is approved. Right now it appears that plan is looking at defeat in Parliament. This brings the possibility of a hard Brexit. Predictions for the UK economy are more dire for this option. The Economist estimates a drop of 7- 10% versus remaining in the EU for a hard Brexit.
The magazine further states the lucrative financial industry of London has already seen firms moving operations to cities such as Dublin, Paris and Frankfurt to handle EU related business. The British Pound will also be affected. Current value seems to have a soft Brexit factored in. Forecasts for a hard Brexit value bring the Pound to parity with the Euro or about $1.15. The current price is about $ 1.28.

Good point about China and their impact on US. I own HOOK, small furniture company, that already is having trouble over the tariff (tax) on what they import for their furniture. I know they are are trying to move their manufacturing to another Asian country but going to take time and capital. And they are small company. 60 minutes had a segment about increasing investment going to China to support AI research and production.

Brexit - the topic of the question - looking like going to be hard Brexit. From what I read in the Guardian, it is going to be years of trade problems for UK let alone how it impacts Scotland (talking Independence again) and Ireland (new border crossing). Medicines,and many other products which come to Britain from Europe via truck. Could take days of sitting in line to cross the border or entrance.
