Nigeria's President Buhari seen in London

Nigeria's president has been pictured in London for the first time since he left his homeland almost 80 days ago.President Muhammadu Buhari, 74, came to the UK for treatment for an unspecified illness.According to the presidency, on Sunday afternoon Buhari received a delegation of “governors and leaders” from his All Progressives Congress (APC) party in London.“The president sends his best wishes to all Nigerians. He will be back to Nigeria as soon as his doctors give the go-ahead,” the presidency said in a separate tweet.Buhari has spent most of this year in London receiving treatment for an unspecified medical condition.In January and February, he spent almost two months in Britain and on his return in early March said he had never been as ill.Buhari left for the British capital again on May 7 for a second round of medical treatment. No date was given for his return.“The President was very cheerful and has not lost any bit of his sense of humour,” said Imo state governor Rochas Okorocha in a press statement issued Sunday by presidential spokesman Femi Adesina.“The party delegation spent more than an hour with President Buhari over lunch, and it was very clear from discussions that he followed developments at home very closely.”The presidency has repeatedly rejected rumours that Buhari is terminally ill or even dead but has refused to disclose his illness or what treatment he is having.The statement said the president "was very cheerful and has not lost any bit of his sense of humour".Governor Rochas Okorocha, who was among the delegation, said President Buhari was asked about the rumours swirling around his health and laughed them off."President Buhari was completely unperturbed by the cocktail of lies. He, instead, sent his best wishes to Nigerians," he said.He added that during the hour-long meeting, the president was fully engaged in discussions on home affairs.Mr Buhari left Nigeria on 7 May - his second trip to the UK for treatment this year.In his absence, he has given Vice-President Yemi Osinbajo full powers to act as head of state.
