Four nutshells of Corbynism (not about the man himself but the ideas and politics he came to symbolise):

1. Emphasis on redistribution of wealth but also power of 'voice' away from City, Westminster and media elite in favour of workers and communities across the country.

2. Wholesale rejection of austerity economics in favour of large scale public investment, democratised ownership and climate renewal

3. Rebalancing the public-private sector through limited nationalisation of key industries and protection of NHS

4. Immigration and foreign Policy based on humanitarianism above all else
