The Parliament’s Secretary-General Klaus Welle described British staff as “valued members of the EU civil service and of our European team” in the email sent in a bid to reassure the administration of the future after Brexit.
British officials will be able to keep their European Parliament jobs after Brexit, Mr Welle wrote in the memo seen by Politico.
He added the Parliament’s administration will “not require British officials to resign on the ground that they will no longer have the nationality of a member state”.
The email added: “Those officials, will thus, be able to stay, and we will continue to benefit from their skills, experience and dedicated work in the future.”
British officials will even be entitled to further pursue their careers, with Mr Welle writing: “I will continue to ensure that the colleagues concerned are offered meaningful career perspectives.”
Meanwhile, temporary and contract British staff will be considered on a “case-by-case assessment”, to be carried out “as soon as possible”.
If it can be justified, employment contracts would be extended, he said.
For accredited parliamentary assistants working for non-British member, a similar “case-by-case assessment” will apply.
According to the Parliament’s staff regulations “employment is terminated if an agent no longer has the nationality of a Member State”.
The Bureau of the European Parliament, an EU body which decides all administrative, staff and organisational matters, has approved the measures, Mr Welle also wrote.
He added: “I am confident that with these decisions, we have ensured certainty for our UK staff, independently of the outcome of the negotiations between the UK and the EU.”
The news comes as the EU’s chief negotiator Michel Barnier took a swipe at the UK following a European Council meeting as he accused British officials of negotiating like they want to join the Brussels bloc.
He told the audience: “Sometimes when I read some UK papers, I would just take example of, not the external security or defence, but the internal security, it seems reading this paper that we have a country who has just begun the process of accession.
“It can not be business as usual. The British paper on internal security, they ask for many opt-ins they’ve never asked for in the past before leaving.”
