In a statement signed by the British High Commissioner to Nigeria, Mr Paul Arkwright recently in Abuja said, a portion of the stolen fund has been returned recently from the UK to Nigeria.
The envoy did not mention the identity of the Nigerian involved in the offence, but said more funds would be repatriated.
He stressed that his country was working with the Nigerian government to accelerate the legal process of returning the looted money.
Mr Arkwright also confirmed that British Prime Minister Theresa May will visit Nigeria, Kenya and South Africa during the week.
May’s visit to Nigeria is part of efforts aimed at boosting post-Brexit trade ties.
The delegation will land in Cape Town on Tuesday, where May will meet South African President Cyril Ramaphosa as well as business leaders and young people.
May will meet with President Muhammadu Buhari in the capital, Abuja on Wednesday and later on, visit Lagos.
