Musician’s Brixton and Dublin performances go viral after she performs Sinéad O’Connor’s anti-racism anthem Black Boys on Mopeds

The UK and Ireland are entering a “dark time”, according to the singer Joy Crookes, who said the influence of far-right ideology on mainstream politics was comparable to the 1970s when the National Front was at its peak.

Crookes, who has just played two sold-out shows at the O2 Academy in Brixton, said the recent wave of nationalism and the far-right march through central London in September made her feel unsafe in the UK.
