It’s being described as a sad day for the BBC. Both Director General Tim Davie and CEO of BBC News, Deborah Turness, have resigned— following controversy over edits to a Panorama documentary about former U.S. President Donald Trump.

In a message to staff, BBC Chair Samir Shah said the resignations mark “a sad day for the BBC,” adding that Davie had been an “outstanding leader” who guided the broadcaster through years of major change. Shah said both leaders had the board’s full support but accepted the “personal and professional pressures” that led to their decisions.

Deborah Turness, in her own letter, said the Trump documentary fallout had “reached a stage where it’s causing damage to the BBC— an institution I love.”

She took full responsibility, saying “the buck stops with me,” but insisted recent claims that BBC News is institutionally biased are “wrong.” Turness thanked her team of journalists for their courage and commitment to reporting “truth with no agenda.”

Outgoing Director General Tim Davie praised Turness for her “extraordinary energy” and for leading a global team of over 5,000 journalists “who report without fear or favour.”

The BBC Board says it will ensure a smooth transition while it searches for Davie’s successor.

Samir Shah ended his letter by reaffirming that the BBC will continue to deliver world-class public service broadcasting, even amid what he called an “unsettling moment” for staff and audiences alike.
