Nigerians often are stuck with decrepit health facilities like this hospital in Maiduguri while paying for President Muhammadu Buhari's and other officials' medical treatment overseas.
The statement by Saraki reads in full: "Myself, Rt Honorable Speaker, Yakubu Dogara and leader of Senate, Senator Ahmed Lawan paid a visit to President Buhari in Abuja House in London".
Sources in the National Assembly confirmed that the leadership of the National Assembly would also discuss issues relating to the 2017 budget, especially the discovery of some frivolous items already slated for removal with the president.
They left Nigeria Wednesday morning and met the president hours after arriving in London.
The Presidency, on Thursday declared that President Muhammadu Buhari will not speak to Nigerians from London because he has right to his vacation.
Saraki said: "The president I saw today is healthy, witty and himself", an apparent attempt to quash speculation about the state of Buhari's health.
President Buhari has been in London since January 19.
The leaders agreed to continue close coordination and cooperation in the fight against terrorism in Nigeria and worldwide.
Trump invited Buhari to visit Washington at a "mutually convenient date", according to Buhari's spokesman Garba Shehu.
"President Trump assured the Nigerian President of United States readiness to cut a new deal in helping Nigeria in terms of military weapons to combat terrorism".
Last week, President Buhari spoke with the Speaker House of Representative, from the Abuja House in the UK.
He had written to the National Assembly informing lawmakers of his decision to extend his vacation, to attend to some health challenges.
He was initially due to return to Nigeria on Monday 6 February.
