Some $5.8m (£4.2m) recovered by UK agencies that was stolen by a Nigerian former governor and laundered in Britain have now been returned to Nigeria, the Nigerian authorities say.
Former Delta state Governor James Ibori was convicted of money laundering in the UK in 2012.
Prosecutors say he stole an estimated $165m (£117m) from the oil-rich state.
A Bombardier Challenger jet is among the items listed in court documents for a confiscation order against Ibori.
The £4.2m has been recovered from Ibori’s wife, sister and fiduciary agent, who were also convicted of money laundering.
Observers expect more money to be retrieved from Ibori himself.
He went to the UK in the 1980s and worked as a cashier at a DIY shop in London.
Ibori was convicted in 1991 for stealing from the store but then returned to Nigeria and got involved in politics.
When he ran for Delta State governor, he lied about his date of birth to hide his UK conviction – which would have prevented him standing for office.
He became governor in 1999 and soon began taking money from state coffers. Delta state is the source of much of Nigeria’s oil.
