The author of this tweet is being misleading, in order to defend his or her previous lie. The current tariff on soya sauce from Japan is zero, due to the EU/Japan FTA which the UK applies until the end of the year. The UK and Japan do not currently trade on WTO terms.
As @ColinYeo1 has pointed out foreign national offenders from an EU country are nothing to do with the asylum system. But I'll add that since @ukhomeoffice officials surely know this, the authors of this tweet are therefore brazen liars who are unfit for public service.
I have emailed the permanent secretary to the Home Office to this end: "Frankly, I find it hard to see how this behaviour is consistent with the civil service code - in particular the requirements of integrity and honesty."
