Government announces plans to invest billions, but questions linger over how its proposals on chips, social media and more will work

London Tech Week, the showcase event for the UK tech industry, focused heavily on that theme this week.

Some represented new commitments and ideas; others appeared to be putting a polish on already announced measures.
