If you can cast you mind back as far as 31st January - I know, it seems a lifetime ago! - Dominic Cummings said Boris Johnson is obsessed with monuments in his memory “like the Roman emperors”.

It is easy to take this too literally: I am sure he would not object to statues and monuments, but major bridges, "Boris Bikes" and things like that are, I guess, equally acceptable to him.   Anything that keeps his fame in perpetuity will do, I expect. That may well be more relevant than whether a bridge between Scotland and Northern Ireland does either of them any good.
