At a launch of his arts programme in Scotland this weekend, the Labour Party leader said ‘he had a deep affection for the work of Mahler and liked other “pretty heavy classical music”.’

He added: ‘I hate the elitism [that says] only the wealthy can go to ballet, only the wealthy can go to opera, only the wealthy can go to Glyndebourne, only the wealthy can enjoy what’s termed highbrow music.’

Would Gustav Mahler love Jeremy Corbyn?
