Talks to allow UK companies to play a greater part in the EU's €150bn (£130bn) defence loans scheme have broken down after a dispute over money.
The two sides had been at loggerheads over a fee to allow British defence firms to access an enhanced share of loans issued under the pact.
The lack of agreement limits the total value of any weapons or parts that UK-based firms will be able to contribute to projects.
The negotiations had been taking place against a Sunday deadline for EU countries to make initial bids for the loans, expected to be issued next year.
