Carl Bildt, former Prime Minister and Foreign Minister of Sweden, with the view from Europe:

What's really going on between the EU and the UK with the UK government threatening to change the so-called Withdrawal Agreement?

Yup, it's really bad. Because what Boris Johnson has proposed is for the UK government to defect and break international law by going away from a substantially important part of the Withdrawal Agreement that has to do with the Northern Ireland peace process. This is a break of trust between the EU and the UK, if it goes ahead. It will have very serious ramifications. And I think if it happens, I think sorry to say, that we are headed for a crash between the European Union and the UK with bad ramifications all across the board. We'll see. Not good.
