The British government has been accused of being “petty” after becoming embroiled in a row over a refusal to grant full diplomatic status to the European Union’s officials and ambassador stationed in London.
Joao Vale de Almeida took up his post as the first EU representative to the UK when Britain formally severed its membership in of the bloc in 2020, but has not been given the same status as other ambassadors.
According to the BBC, the Foreign Office intends to treat EU officials as representatives of an international organisation on the basis that it is not a nation state and is insisting staff should not be afforded diplomatic privileges.
Brussels said Britain was “well aware” the EU's 143 delegations and staff in other parts of the world had been accorded a status equivalent to countries' embassies under the Vienna Convention, which governs the rules of international diplomacy.
Without the full protection of the convention, diplomats do not benefit from immunity from detention, criminal jurisdiction and taxation.
The EU’s high representative for foreign affairs Josep Borrell wrote to Dominic Raab, the foreign secretary, in November expressing his “serious concerns” over the decision.
“Your service has sent us a draft proposal for an establishment agreement about which we have serious concerns," he said.
“The arrangements offered do not reflect the specific character of the EU, nor do they respond to the future relationship between the EU and the UK as an important third country.
“It would not grant the customary privileges and immunities for the delegation and its staff. The proposals do not constitute a reasonable basis for reaching an agreement.”
Tobias Ellwood, the Conservative chair of the Commons Defence Committee, described the decision as “petty”, adding: “[Joe] Biden commits to strengthening alliances and we engage in silly spats which will not help strengthen security and trade cooperation. We are better than this.
Peter Ricketts, a former national security adviser and head of the diplomatic service, added: “I came to the same conclusion.
“This is a wholly unnecessary move which seems part of systematic effort to signal that the UK is shunning the EU and all its works. Not in British interests.”
European Commission spokesman Peter Stano told the BBC that the UK, which, as a member of the EU, was a signature to the Lisbon Treaty which established the European External Action Service diplomatic network, was "well aware of the EU's status in external relations".
"Nothing has changed since the UK's exit from the European Union to justify any change in stance on the UK's part," he said.
"The EU's status in external relations and its subsequent diplomatic status is amply recognised by countries and international organisations around the world, and we expect the United Kingdom to treat the EU Delegation accordingly and without delay."
