I caught the tail end of a BBC Radio 5 phone in with Simon Hughes last night and the Lib Dem policy for an amensty for illegal immigrants who've lived here for 10 years (IIRC) was being scrutinised.
Apparently there were questions raised, but few clear answers given, about how these people would be able to prove they'd been here that long and what'd happen to those who'd been employing them during that period. It also appears that any 'amnestees' won't be expected to pay back tax in the same way that a UK citizen who'd been found working illegally probably would. If their policy is as unfair and half baked as it appears, it'll be food and drink to their political opponents I'd have thought....
I haven't yet listened to the whole programme but am hoping I'll be able to do so on iplayer later.
