Cat Hobbs is the founder of We Own it, which describes itself as a voice for public service users who want public ownership. Paul Massara is the the former chief executive of RWE Npower. They discuss the merits and pitfalls of nationalisation and its implications for investment in the UK. (Image: Jeremy Corbyn. Credit: Getty Images)
