Today has announced this year’s Guest Editors, with seven taking over the programme during the festive period, including Nazanin Zaghari-Ratcliffe, ABBA’s Björn Ulvaeus and Jamie Oliver.

For the past 19 years, the programme has handed over the editorial reins to high-profile public figures during the week between Christmas and New Year.

This year’s line-up includes:

Nazanin Zaghari-Ratcliffe – British-Iranian national who was detained in Iran

Björn Ulvaeus – ABBA legend

Jamie Oliver – Chef and campaigner

Sir Jeremy Fleming – Director of Government Communications Headquarters (GCHQ)

Dame Sharon White – Chairman of John Lewis Partnership

Lord Botham – Crossbench Peer, UK Trade Envoy to Australia and former cricketer

Anne-Marie Imafidon – Technologist, CEO and author

They will each guest edit Today between 26 December and 2 January and each programme will include an interview with the Guest Editor. All of our guest editors have started working on their programmes and shared some messages. Today's Martha Kearney also spoke to Björn Ulveaus about why he wanted to guest edit the programme.
