After more than a decade-long process, steps by the British authorities to confiscate money stolen by a Nigerian former state governor, James Ibori, have nearly concluded, the Reuters news agency reports.

It quotes a British prosecutor as telling a court that it should retrieve $129m (£100m) from Ibori.

Previously, prosecutors have said that he stole an estimated $165m from the oil-rich Delta state in southern Nigeria.

Two years ago, the UK returned some $5.8m that Ibori had taken.

In 2012, after being extradited from Dubai to the UK, he was convicted on 10 counts of fraud. After serving some of his sentence in prison Ibori returned to Nigeria in 2017.

In a text message to Reuters he said that he would appeal against the confiscation order.

It is expected to be issued on Friday or soon after, Reuters says.
