TV personality Sharon Osbourne has left US chat show The Talk after a heated on-air debate about racism earlier this month.

Osbourne defended broadcaster Piers Morgan over his criticism of a high-profile TV interview given by the Duchess of Sussex.

That led to a clash with co-host Sheryl Underwood, who accused Osbourne of giving "validation" to "racist" views.

TV network CBS took The Talk off air while it carried out an investigation.

In a statement on Friday, CBS said the events of the 10 March episode "were upsetting to everyone involved, including the audience watching at home".

It said Osbourne's behaviour towards co-costs during the episode "did not align with our values for a respectful workplace".

The review did not, CBS said, find any evidence to support Osbourne's allegation that the controversial discussion had been "orchestrated" by producers.

However, CBS said it acknowledged the network, studio teams and producers were "accountable for what happened during that broadcast" because "it was clear the co-hosts were not properly prepared by the staff for a complex and sensitive discussion involving race".
