Conservative finalist Liz Truss could face an “accidental escalation” in Brexit talks with the EU, as the most conservative wing of the Conservative Party could push her to adopt an uncompromising stance, broadcaster Salma Shah said. Ms Truss has upped the ante with the EU by passing through Parliament the Northern Ireland Protocol Bill – a bill aimed at scrapping the Irish Sea border, which would flout the agreement negotiated with the EU and as a result, potentially provoke a trade war.
