Now with towns and cities across the UK forced to address the darker side of their history – there are moves to review statues and streets named after controversial figures, many involved in the slave trade or colonialist past.
In Glasgow – as well as protests – a billboard has been erected in the city centre with the names of thousands of people who’ve died in racist attacks or in police custody.
Among the statues attracting controversy there – Frederick Roberts – a 19th century military leader who’s accused of helping to set up concentration camps.
