"There's far more businesses moving to the UK rather than away from it because of brexit"
You have actual evidence of this?
I mean real statistics gathered by impartial observers?
Because there is actual evidence of JLR relocating to Slovakia and BUPA relocating part of its operation to Dublin and Somerset Asset Management (Prop. J Rees-Mogg) setting up a branch in Dublin rather than growing in London
Do tell whose coming to the UK.
