Could be interesting. Biden does not seem to want to hang about – so Northern Ireland will possibly be explosive. Diplomats like to prevaricate, but Biden seems to want some action. Trade deals are imperative for the Johnson crew, so threats to that could make interesting reading. Johnson seems to want to keep tax issues as distant as possible whilst Biden has said he wants to increase them (Bezos, Buffet, Musk and 22 other very rich, paid just 3.4% tax over the last 5 years). I am not sure Israel will come up for discussion – but again could be interesting. Will the USA exert a greater influence over proceedings now that Trumps shadow is receding.
