Racingsparrow The whole point is that Teresa May did not get a deal - that is why she resigned. Anyway the devil is in the detail, and Boris is not a details man. It is not the broad headline policies he cocked up, but he was prepared to sell Britain cheap including fudging the details (like Northern Ireland) so everything sounded good, hence the vote in Parliament, but once it was through the wheels began to come off, because they were not properly fixed.
What has Tony Blair negotiating the Northern Ireland Protocol got to do with it? That happened years ago, before Brexit was more than a mote in Nigel Farage's eye. It has worked very well and formed part of the Good Friday Agreement, which was not perfect, which was admitted and known at the time, but did end most of the sectarian violence in Ireland.
I quite agree our PMs and Leaders of the opposition for last 15 years have been the scrapings at the bottom of the barrel. The last PM with any credentials for statesmanship was Gordon Brown - and he was, sadly, not a success.
