The United Kingdom said it would return to the European Union’s 95.5 billion euros (103 billion dollars) Horizon science research programme, following months of negotiations.

The government said a “bespoke’’ new agreement has been signed off with the EU, with British researchers able to apply for grants and take part in Horizon projects.

Prime Minister Rishi Sunak said: “ we have worked with our EU partners to make sure that this is the right deal for the UK, unlocking unparalleled research opportunities. And we also have the right deal for British taxpayers.

The British government said the deal includes a “clawback” mechanism, which means the UK will be compensated if British scientists receive significantly less money than it puts into the programme.

The move was welcomed by scientists, amid warnings that UK researchers have been missing out on collaboration with colleagues in the EU, Nicola Perrin, chief executive of the Association of Medical Research Charities (AMRC), said.

“Finally the news we’ve been waiting for the UK is rejoining Horizon Europe. “ Ongoing government commitment to cross-border collaboration in research is crucial to deliver benefits to patients .

“The announcement will be a huge relief to charities and the researchers they fund.’’

Similarly, European Commission President Ursula von der Leyen, who signed off on the deal with the Sunak in a call on Wednesday, said.

“The EU and UK are key strategic partners and allies and today’s agreement proves that point. “We will continue to be at the forefront of global science and research.”
