The identities of the two other governors, who are expected to come from the North-East and North-Central could not be verified.
He added that he was surprised when he heard about the journey from one of his counterparts, stating that if the secretariat and the governors had been contacted, the governors would have picked at least one of the PDP governors that had been critical of the President.
Sundiata Post further recalls that former Aviation Minister, Chief Femi Fani-Kayode had earlier faulted the alleged visit of Governor Rochas Okorocha-led APC governors team to London, describing the picture making rounds in that regards as fake and old.
Meanwhile, the purported visit of the PDP delegation is coming in the face of some criticism from the Leader of the PDP Governors and Ekiti State Governor, Mr Ayodele Fayose.
The governors are expected to have lunch with the President before returning to the country on Wednesday.
The visit comes a few days after President Buhari hosted the leadership of the All Progressives Congress (APC) and some governors elected on the party's platform, on Sunday in Abuja House, the British capital.
Amid conflicting reports on the health of the 74-year-old president, his office released a photograph on Sunday - the first for nearly three months - showing a smiling Buhari looking less gaunt than when he was last seen on television in Nigeria.
The presidential aide said Buhari's acceptance of the nomination was contained in a letter of appreciation addressed to President of Guinea, Alpha Conde. Others have anxious he may not be able to return to duty.
Okorocha earlier said Buhari had laughed off rumours concerning his health when asked about them.
A thin-looking Buhari was last seen in Nigeria on state television welcoming a group of 82 girls released by Islamist militant group Boko Haram, just hours before he flew to Britain to begin his medical leave.
