The world is bracing itself for what Donald Trump is calling 'Liberation Day' when on 2 April he's promised tariffs will be placed on most countries trading with the US.   
 
The UK is already feeling the effects of Trump's protectionist policies after tariffs were imposed on its metal industries.   
 
On the Sky News Daily, Niall Paterson speaks to economics and data editor Ed Conway who has been travelling across the UK looking at the impact they're having so far.  He visits an aluminium plant in Scotland and a stainless steel producer in Sheffield, both hit by the tariffs, but finds there is some hope for a tungsten mine in Devon.
