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

'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.
