One of the men who hounded Anna Soubry used to be a keen Jeremy Corbyn supporter, it emerged last night.

Max Hammet-Millay was part of the mob of protesters who surrounded the Conservative MP on Monday, calling her a ‘Nazi’ and a ‘traitor’. He was pictured grinning and wearing a red cap as he was detained by police officers outside the Houses of Parliament.

The 21-year-old showed little remorse for his actions yesterday as he took to Facebook to share a photo of Miss Soubry with a drawn-on Hitler moustache.

Hammet-Millay – a Russian orphan who was adopted in London – has recently shared a slew of anti-immigrant messages on the social networking site, including one saying: ‘If you return migrants to the land they came from there would be no encouragement for others. Action required PM.’

Other posts call Labour politicians Jeremy Corbyn and Diane Abbott ‘morons’.

But it appears the politics of Hammet-Millay – who was privately educated at £23,000-a-year DLD College in Westminster – have significantly evolved over the past couple of years.

A month after the EU referendum, he was pictured holding a ‘Jeremy Corbyn for PM’ placard at an anti-austerity demonstration.

In August 2016, he shared posts in favour of the Labour leader, including one praising him for announcing ‘1 million new jobs’.

It is not clear what caused his politics to shift so dramatically.

He recently shared a post on Facebook saying: ‘White families are a beautiful thing – love your race, stop white genocide.’ He also regularly posts offensive comments about Islam.

Hammet-Millay came to Britain from an orphanage in Russia after being adopted by a gay couple – Glenn Hammet and architect Keith Millay.

The couple from Islington, North London, adopted another boy from the same orphanage two years before Hammet-Millay. In 2017, they said they regretted adopting the boys. They told the Mail on Sunday their lives had been turned into a ‘nightmare’ which left them ‘physically, emotionally and financially destroyed’.

Hammet-Millay’s Facebook profile says he studies biology at the University of Portsmouth and lives in Camden Town, London.
