Yes and no, maybe. You are right that this current flavour of tax avoidance is not going to work anymore and moving to London now or in the future will not change the outcome for the money mentioned here, only future money. However about London, once outside the EU they will have the opportunity to position themselves as a tax haven with clever new tax avoidance scheme for large companies. Now you probably automatically dismissed the idea because that's a crazy idea. Setting up yourself as a tax haven does not scale to the size of the UK economy, and the UK would need to do it at a time of intense scrutiny by the global community and the EU will certainly see that as a aggressive negotiation tactic which is not going to help the Brexit negotiation. But well, there were better arguments for not leaving the EU in the first place, and yet the UK seems to merely go for the hardest Brexit possible. So who knows ? McDonald (fiscal) move to London is worrying. Nissan and others are a bit too happy after their secret chat with the PM.
