An Ethiopian cultural surge – including a first national pavilion at the Venice Biennale and the rise of stars such as Ruth Negga and The Weeknd – is making the country’s calls for restitution of looted colonial-era artefacts harder to ignore, according to Lemn Sissay.

The poet and author, who is curating the country’s inaugural Biennale pavilion, where Tesfaye Urgessa’s work will be on show, said the event would be part of a significant cultural push from the east African country and its diaspora over the last two decades.

British celebrities have urged Commonwealth leaders in Rwanda to oppose the UK’s plan to deport refugees to the country, saying it shows a “colonial view” of Africa as a “dumping ground”.

It comes as a summit of Commonwealth prime ministers and presidents is under way in Kigali, the first time the gathering has been held since 2018.
