Like it or not, Digwa and his brother are British.
just because his parents arrived here [no doubt when why how to follow] & he was born here this unfortunately ticks the this box
they really are not
a british passport for them both is a disgrace
it should be permission to stay at best
the two of them brandishing a british passport [BP] after being on their travels is a disgrace
this lessens the value of the BP
not that Digwa will be needing a passport anytime soon revoke it
& deport him when he finishes his sentence
in the meantime he;s just maybe had a prison welcome boiling water avec sugar added
