"Here, the doctor is absolutely in charge", he said.
President Muhammadu Buhari has said though he wants to return home, he will have to wait for the doctor' orders to do so, indicating that he may not be returning to the country soon.
The aides are Femi Adesina, senior special adivser on media and publicity, Lai Mohammed, minister of information; Garba Shehu, senior special assistant on media and publicity; Lauretta Onochie, personal assistant on digital/online media and Abike Dabiri-Erewa, senior special assistant on diaspora matters.
In a statement issued on Saturday by his Special Adviser on Media and Publicity, Mr Femi Adesina, the President said he wishes to return home, "but I've learnt to obey my doctor's orders, rather than be the one issuing the orders".
Among those who visited Buhari at the Abuja House in London in recent times included Acting-President Yemi Osinbajo, state governors, leadership of All Progressives Congress (APC) and some prominent Nigerians.
That has sparked numerous protests, including demands that Buhari should resign, as well as calls for more transparency about the president's condition. "I've now learnt to obey orders, rather than be obeyed".
President Muhammadu Buhari has disclosed that his health has tremendously improved but he is only waiting for his doctors to give the green light before he returns home.
Accompanied by photographs of Buhari and his media team exchanging banters in London, the statement also quoted Buhari as thanking his country folks and other Africans for praying for his recovery. "May God reward them", the president.
Meanwhile, a group, The True Democrats in Nigeria, says National Grand Solidarity Walk In Support of Buhari/Osinbajo Administration holds tomorrow at Unity Fountain, Abuja.
The presidency also released photos of Buhari walking outdoors.
