Children of failed asylum seekers in Britain could be taken into care from today if their parents refuse a free flight home.
The Asylum and Immigration Act (Treatment of Claimants, etc) Act withdraws support from families who have failed to win asylum and refuse to return to their home countries.
A spokesman for Britain's Home Office said it was impossible to say how many families could face withdrawal of financial support and accommodation, but stressed that it was unlikely to happen over the next few days.
"We're working to encourage families to take the dignified option of returning home," he said. Decisions will be made on a case-by-case basis.
Children could be taken into social services care under existing child welfare rules if their parents deliberately make themselves destitute by staying in Britain.
Other measures coming into force today include up to 14 years in prison for those who smuggle people into the UK for forced labour or organ removal. Britain's immigration minister, Mr Des Browne, said that the new penalty sent a "clear message" to those involved in trafficking.
