Other names that will be celebrated in the London scheme from English Heritage are novelist Barbara Pym, artist Graham Sutherland, ballerina Alicia Markova and Jamaican writer and campaigner Una Marson.
More London locations will be picked for Marson, claimed by the BBC to be its first black producer on the payroll who would go on to develop Caribbean Voices, part of the Calling The West Indies series, as well as Excellent Women author Pym.
An episode of Netflix royal drama The Crown revolved around the creation of the painting, and last year Sutherland’s preparatory painting of Churchill was sold by Sotheby’s auction house for £660,000.
Sutherland – known for his controversial 1954 portrait of Winston Churchill that was later destroyed – will be honoured at his childhood home in the suburbs of London.
Elsewhere, T Rex frontman Bolan, who died in 1977 after a car crash, aged 29 will be marked with a plaque at one of his west London addresses.
