An immigrant childminder who killed a toddler in her care was given £4,500 to return to Malaysia after she was released from prison.
Agnes Wong, 29, was convicted of the manslaughter of 17-month-old Hugo Wang at Manchester Crown Court in January last year.
She was jailed for five years but was freed in July this year after time spent in custody was taken into account.
Two weeks ago, Wong left the UK on a plane from London Heathrow and went back to her home country with a "voucher" worth £4,500.
The little boy died of a brain injury in January 2007 inflicted while Wong was looking after him.
Wong had swung Hugo by his ankles and smashed his head, the court heard. He also suffered bite marks, bruising and burns caused by a hairdryer.
Tory immigration spokesman Damian Green told the Mail on Sunday: "For an immigrant who killed a child to get taxpayers' money to help with her future life is nothing short of appalling."
Wong was paid through the Government's assistance scheme for reintegration, which is worth up to £5,000 for serving foreign criminals and £3,000 for time-served.
She applied for the one-off payment, intended to enable convicted foreigners to leave the UK quickly without becoming costly in the long-term, before she completed her sentence, according to the Home Office.
David Wood, the UK Border Agency's director of criminality and detention, said: "We don't want foreign criminals in the UK. Every day that we can get these individuals out of the country early removes the risk they present to UK citizens and saves our taxpayers over £100 a night in detention costs as well as administrative and court costs."
