DUP leader Arlene Foster is to appear on the BBC's flagship politics programme, the Andrew Marr Show, on Sunday morning.
The weekly politics show will air on BBC One at 10am.
Mrs Foster last appeared on the programme in May where, in a wide-ranging interview, she discussed Brexit, her party's confidence and supply deal with the Conservative government and attempts to restore power-sharing at Stormont.
The latest interview is likely to focus on the DUP's continuing opposition to the draft Brexit withdrawal agreement.
In an interview with the BBC on Wednesday Arlene Foster said that, while the confidence-and-supply deal between the DUP and the Conservatives is not dead, Prime Minister Theresa May "needs to rethink" the agreement.
