• English Heritage has unveiled its 1000th Blue Plaque in London. The plaque – located on a three storey building at number 1, Robert Street in Westminster – marks the former London headquarters of the suffragist organisation, the Women’s Freedom League. The league, which was formed in 1907, worked out of the building between 1908 and 1915 – its most active period. The blue plaques scheme has been running for more than 150 years and honours everyone from John Keats and Charles Dickens to Ada Lovelace and Alan Turing.

• A major new work by Chris Ofili commemorating fellow artist Khadija Saye and the tragedy of the Grenfell Tower fire in which Saye died, has gone on display at the Tate Britain in Millbank.  Requiem, a site-specific work which is shown across three walls, is described as a “journey through an imagined landscape of giant skies with vast horizons and flowing water” which unfolds in three chapters. Ofili says that when making the work, he recalled the feelings he had when creating No Woman, No Cry in 1998 as a tribute to murdered Black teenager Stephen Lawrence and his mother Doreen. “That feeling of injustice has returned,” he said. “I wanted to make a work in tribute to Khadija Saye. Remembering the Grenfell Tower fire, I hope that the mural will continue to speak across time to our collective sadness.” For more, see  tate.org.uk/visit/tate-britain.
