Abuja, 23 Jan-(ANA)-

The president has been in Saudi Arabia for two months, receiving treatment for a heart condition.

The court ruling directed the cabinet to pass a resolution about whether he "is incapable of discharging the functions of his office".

The president's absence has raised concerns about a power vacuum.

The Federal High Court ruled that cabinet should hear testimony from five doctors, one of whom should be the president's personal physician.

If cabinet decides that the president is not fit to carry out his duties, the vice-president would take over, the court ruled.

The court was responding to a law suit brought by opposition activist Farouk Adamu Aliyu.

He had asked for the judges to sack the president over his failing health and for failing to abide by the provisions of the constitution. (ANA)
