'No one is irreplaceable', says BBC chief after scandals

BBC director general Tim Davie has said he is "not letting anything lie" when it comes to rooting out abuses of power within the corporation.

"If you're not living the values, it is clear you leave the BBC or there are consequences," he told MPs on Tuesday, adding that no one was "irreplaceable".

Davie is facing questions from the Culture, Media and Sport Committee on a number of scandals.

One of the topics discussed was the MasterChef crisis, after both of its presenters - Gregg Wallace and John Torode - were sacked following a report which upheld allegations against them.

During the hearing, Davie discussed some of the changes that have been made to how abuses of power are dealt with following a recent review into the BBC's workplace culture.

"There are consequences, we are not mucking around now," he said.

He insisted the report had shown that the BBC does not have "a toxic culture".

But he also said there were "pockets where things were not right".

Davie would not comment on whether there were currently further scandals about workplace behaviour and abuses of power brewing.

He also said he couldn't guarantee there would never be someone else abusing their power.

"Because culture is ongoing," he said. But he added that he thought "we're at a moment in society where we're calling it out".
