Britain must pay to join a European Union defence fund, according to reports.
The UK and the EU are set to sign a defence and security deal at a summit next month.
But a second agreement will be required before British companies will be able to bid for the new €150 billion EU defence fund, according to diplomats and officials involved in the negotiations.
An EU diplomat told the Financial Times: “The pact is a nonbinding instrument. The more difficult hurdle is going to be a bilateral agreement that would include a financial contribution.”
