Criticisms of Corbyn’s policy so far have tended to focus on the risk of job losses or the policy’s vaguely communist flavour. But increasingly, the internet is also the public square within which our political debates are conducted. What about the potential downsides of leaving that public square entirely under government control?

I am a long way from being a free-market ideologue when it comes to the delivery and funding of public infrastructure. But the example from Iran should give us pause. Are we truly confident that a Corbyn government, or indeed any government, would not be tempted by a handy ‘Off’ switch for public political discussion if that discussion did not seem to be going the government’s way? If we have any doubts whatsoever we should think twice about getting behind the nationalisation of British broadband.
