Rishi Sunak has issued a veiled warning to Boris Johnson not to undermine his new Brexit deal - insisting it isn't about "personalities".
The Prime Minister admitted that the controversial Northern Ireland Protocol - signed by Mr Johnson - needed fixing as he mounted a charm offensive to promote his Brexit agreement.
After years of Brexit wrangling, Mr Sunak and EU chief Ursula von der Leyen struck a new deal yesterday aimed at ironing out trading issues in Northern Ireland caused by the UK's departure from the EU.
