This is from the guardian - interview with Alex Norris, the border security and asylum minister
When Nick Robinson, the presenter, put it to Norris that this means that the 20-year would in practice apply to almost no one, and that the government was just trying to send out a “tough message”, Norris said he did not accept that. He went on:
Let’s not forget, I’m afraid, that of those who have successful [asylum] claims, 50% of them end up on benefits.
50%! that’s crazy!
