President Bola Tinubu has extended his working vacation in Europe by a few days and is expected to return to Nigeria this weekend.

The Presidency says Tinubu has remained in contact with developments in the country and continues to direct government affairs while away.

It says the President recently ordered an independent investigation into the deaths of 37 suspected illegal miners who died while in the custody of the NSCDC in Minna, Niger State.

Vice President Kashim Shettima has been representing Tinubu at some official events but is currently in New York for the 81st United Nations General Assembly.

The Presidency says Secretary to the Government of the Federation, George Akume, will continue to represent the President at other official engagements.

Meanwhile, former Vice President Atiku Abubakar has questioned who is constitutionally exercising presidential powers while both Tinubu and Shettima are outside Nigeria.

Atiku cited Section 145 of the Constitution, arguing that Nigerians should be shown the formal declaration transferring presidential authority to the Vice President as Acting President.
