Brexit , borders and lorries

Why would Sir Ratcliffe be moving out of the country now?

He voted for Brexit, was a huge proponent of Brexit, he got what he wanted, and now is abandoning his Brexit paradise and moving to tax free haven of Monaco after moving his car production plant from Wales to the EU?

I thought he was opposing EU, wanted to make the UK strong and successful country, so he should be investing in this country, paying his taxes in this country, especially that he got the Brexit vote, he so advocated for, people listened to him, followed his lead, voted the way he wanted , and now he is leaving the Brexit paradise?

Who is going to be supporting this Brexit paradise when all the rich Brexiters are abandoning the ship?
