President Muhammad Buhari said Biafra agitator, Nnamdi Kanu must defend himself in court.
The leader of the proscribed Indigenous Peoples of Biafra (IPOB) is facing trial in Nigeria.
The Nigerian government slammed treason charges against him after repatriation one year ago.
On Thursday, Buhari spoke about Kanu in a chat with British Prime Minister, Boris Johnson.
The President stated that it was untrue that Kanu was not allowed not allowed to see his lawyers privately.
Buhari said the separatist was being given every opportunity under the law to justify the “uncomplimentary things” he said against Nigeria while in the UK.
“He felt very safe in Britain, and said awful things against Nigeria.
“We eventually got him when he stepped out of the United Kingdom, and we sent him to court.
“Let him defend all that he has said there. His lawyers have access to him.
“Remember he jumped bail before, how are we sure he won’t do it again, if he’s admitted to bail”, he quipped.
