LONDON (Reuters) -A deal for Britain to rejoin the European Union's Horizon scientific research scheme has been negotiated and is now awaiting approval from Prime Minister Rishi Sunak, the BBC said, citing sources.

The UK government has been negotiating with the EU over rejoining Horizon after London and Brussels settled their dispute over post-Brexit trade rules governing Northern Ireland in February.

Asked about the report, a British government spokesperson said: "Talks are ongoing and therefore we have not yet agreed a deal."

British research scientists are keen to rejoin Horizon.

The BBC cited "highly placed sources" as saying an agreement had been reached over how much funding the UK should provide and there are now two options for associate membership for Sunak to consider.

If he approves the deal, it could be announced on Tuesday following talks scheduled between Sunak and European Commission chief Ursula von der Leyen.
