at the corporation by 2020". Indarjit Singh, the chief of Britain's Network of Sikh Organisations, criticised the BBC Asian Network, a radio station intended for an audience of South Asian origin: "Stations like BBC Asian Network do little to encourage integration and social cohesion because they allow communities to ghettoise themselves". In September 2019, the BBC's Editorial Complaints Unit upheld a complaint that television presenter Naga Munchetty breached their editorial guidelines in her criticism of racist comments made by US President Donald Trump about four US representatives. That decision was criticised by the BBC's black and ethnic minority (BAME) network, and 44 British actors, broadcasters and journalists of BAME origin wrote a letter to ask for the BBC to reconsider its decision.

The BBC has defended the use of the word nigger in response on 4 August 2020, saying it wanted to report the word allegedly used in the attack of K-Dogg, and this decision was supported by the family of the victim, but the corporation accepted that it did cause offence. On 8 August, Sideman, real name David Whitely, said he had decided to leave BBC Radio 1Xtra because of the use of the racial slur and the defence of it. The next day, 9 August, the BBC apologised over the use of nigger and said
