Re: HS2 and the Galileo replacement
Most of them aren't own by Britain, they are own by foreign companies or even worst own by companies effectively control by foreign governments both only care about themselves. They have no loyalty to the UK and will move to where the work is, which Airbus has already announce it will do for Galileo. The UK only tool to fighting this is really deny export licenses for technology on security grounds but that so anti business that Tories funders are unlikely to be happy with the tories doing this and could well withdraw there funding for the Tories, even if that risk Corbyn getting in.
Tories really are the worst party you could imagine to implement a successful Brexit as everything you need to do a successful Brexit goes directly against core Tory ideology.
