The first cabinet meeting that Nigeria's President Muhammadu Buhari was due to attend since returning from three months' medical leave in the UK has been cancelled, his special adviser Femi Adesina has said in a statement.

He did not give any reasons for the decision, but Mr Buhari, 74, has been working from home since he returned to Nigeria on Saturday.Government spokesman Garba Shehu said his office required renovation because rats damaged the furniture and air conditioning in his absence.

Mr Adesina said Mr Buhari would receive a report from a panel which investigated allegations of corruption against two suspended oficials - National Intelligence Agency chief Ayo Oke and government secretary Babachir Lawal.

The panel is headed by Vice-President Yemi Osinbajo, who was acting president in Mr Buhari's absence.Some Nigerians had called for him to resign during his prolonged absence, saying he was unfit to run the country.

Others were angered by officials' refusal to disclose what Mr Buhari was treated for.
