Sir Keir warned not to cosy up to EU

Sir Keir Starmer was yesterday warned against more Brexit backsliding after Donald Trump threatened to hit the EU with 50 per cent trade tariffs.

The US President made the threat amid trade talks between Washington and Brussels, warning he could impose the tariffs next month.

It comes after Sir Keir unveiled his EU-UK 'reset' deal this week, bringing Britain the closest its been with the bloc since Brexit.

But critics fear it's the start of a slippery slope which could lead to the PM, who tried to reverse Brexit while in Opposition, taking Britain back into the EU's customs union or single market.

Were this to happen, the tariffs would likely apply to the UK too.As part of his deal, dubbed the 'surrender' pact by Brexiteers, Sir Keir agreed to shackle Britain to the EU's rulebook on food standards, also known as the Sanitary and Phytosanitary Agreement (SPS).
