Nigerian leader Muhammadu Buhari will embark on another trip to London on Tuesday for a medical check-up, his spokesman said on Monday. This time, Buhari will spend only four days in the United Kingdoms capital, said presidential spokesman Garba Shehu. He said Buhari had a brief meeting last week with his doctor in London when he had a technical stop-over for his aircraft maintenance on his way back from Washington after a state visit to the United States. The doctor requested the president to return for a meeting which he agreed to, Shehu said, adding Buhari would return to Nigeria on Saturday. In January 2017, the Nigerian leader embarked on a medical vacation in London and returned later than he planned. Upon arrival in Abuja, he confirmed that he was seriously ill and had never felt so ill in his life. On May 7 last year, exactly a year ago, he made another visit for treatment in London and returned home 103 days later.
