Fans of Robert Peston will be disappointed to learn his new political show will not hit our screens over the "next few months". ITV has yet to appoint a production company for Peston On Sunday and no air-date has been decided, the broadcaster told IBTimes UK.

"It won't be in the next few months because it will take a little while for them to work out what they want to do with it," an ITV spokeswoman explained. The broadcaster previously revealed the morning programme will not clash with The Andrew Marr Show, which usually airs between 9am and 10am (GMT) on BBC1.

But Peston On Sunday is still expected to launch in 2016 after the journalist jumped ship from the BBC, where he had been economics editor since October 2013. The 55-year-old succeeds Tom Bradby as ITV's political editor and will start work at the broadcaster on 11 January.

Geoff Hill, editor of ITV News, said: "I'm delighted that Robert is joining us at such an important time as we continue to develop News At Ten. He is a hugely respected and competitive journalist, renowned for agenda-setting journalism. Our news programmes will benefit greatly from his distinctive style and his political expertise, and his appointment sends out a clear message about our ambitions."

Peston, who started his career at the Investors Chronicle, faces strong competition among the Sunday politics shows. Dermot Murnaghan's programme on Sky News airs just after the Marr show at 10am and the BBC's Sunday Politics, hosted by Andrew Neil, usually hits screens at 12pm on BBC2.
