The Government has admitted Parliament will need to approve the £1bn funding package promised to the Democratic Unionist Party (DUP) in the wake of the election.
The admission comes in response to a challenge mounted by prominent anti-Brexit campaigner Gina Miller, who has asked what legal basis the Government has for releasing the as-yet-unavailable funds.
The sum was agreed in negotiations between the Conservative Party and the DUP as part of a "confidence and supply" agreement.
It became necessary for the Government after the June vote returned a hung Parliament, destroying the Tory majority.
A solicitor for the Treasury gave a statement in response to a letter filed by Miller and the Independent Workers Union of Great Britain (IWGB).
Jonathan Jones made clear the Government would follow the established procedures to ensure the funding would have the authorisation of Parliament, and said a timetable for making the payments had not been made.
The claim made by Miller and the Union has been deemed urgent by the High Court, and is expected to be heard in late October.
