According to the coalition, the solidarity walk became necessary following the recent and unfortunate political happenings in Nigeria bordering on the news peddled about the medical vacation of President Muhammadu Buhari.
"Here, the doctor is absolutely in charge", Adesina quoted the President as saying.
Presidential spokesman, Mr Femi Adesina, in a statement, said Buhari spoke yesterday while receiving his media team and the Senior Special Assistant on Diaspora Matters, at Abuja House, London.
Buhari said he was following events in Nigeria and understands that there are protests against his continued stay in London. "I have now learnt to obey orders, rather than be obeyed".

Federer hammered five aces, made just two double faults and won 81% of his first serve points in the 68-minute centre court match. For nearly two decades, spectators have flocked to Federer's breathtaking matches and followed the ebb and flow of his career.
Nigeria's President Muhammadu Buhari says he feels healthy enough to return home from medical leave in Britain, and is awaiting his doctor's permission.
When told that prayers were going on fervently for him, not only in Nigeria, but all over Africa, and round the world, a delighted President said: "What we did in The Gambia early this year fetched us a lot of goodwill on the African continent". I thank all those who are praying. "May God reward them", the president. In another photograph, they were all smiles as the president took a stroll on the forecourt lawn.
If Buhari does not stand, it could also lead to greater ethnic and religious tensions in Nigeria, long riven by divisions between the largely Muslim north and the mostly Christian south.
Opposition figures and recently some Christian clerics have called on him to resign if he is too weak to continue in the saddle.On Monday, a daily sit-out of dozens of activists calling on him to return home or resign began in the capital city Abuja. The pro-Buhari group insisted he had complied with the constitutional provisions by transferring power to his deputy and had not fouled any law, the same position held by the Senate.
