The president stated this when he faced questions from State House correspondents on Sunday shortly before leaving the presidential wing of the Nnamdi Azikiwe International Airport in Abuja for London.
The News Agency of Nigeria (NAN) reports that the president had initially planned to make the trip to London from Nairobi, Kenya, after attending the United Nations Environment Programme (UNEP) conference in that country on Friday.
The president said, “Well, they (critics) should wait and see. How did we, as a party, come to take power from the ruling party that was there for so many years before us?
“We have the ability to do it, everything will be fine,” he said.
On his trip to London, Buhari said his absence would not affect the work of government because the vice president, who is assisted by the secretary of state and his chief of staff, is in charge.
“Well, I cannot say I am doing the work alone. The government is fully represented – the vice president is there, and when I’m not there, according to the Constitution, he’s in charge; and the secretary of government, and then the chief of staff. So, no problem.”
Presidential spokesman Femi Adesina had said in a statement on March 1 that the president’s trip to London for routine investigations would “take a maximum of two weeks.”
