‘We’ve removed 23,000 ghost workers from our payroll,’ President says

Buhari made the comment while speaking at an anti-corruption conference in London today, May 11, 2016.

He also spoke on steps that his administration had taken to curb corruption.

“We have implemented the Treasury Single Account whereby all federal government revenue goes into one account,” Buhari said.

“This measure would make it impossible for public officers to divert public funds to private accounts as was the fact before. We have been able to remove 23,000 ghost workers from our payroll thereby saving billions that would have been stolen,” he added.

Buhari also said that he would not demand an apology from British Prime Minister, David Cameron after the latter described Nigeria as .

"No. I am not going to demand any apology from anybody. What I am demanding is the return of assets," Buhari said according to BBC.

"I have already mentioned how Britain really led and how disgraceful one of the Nigerian executives was. He had to dress like a woman to leave Britain and leave behind him his bank account and fixed assets, which Britain is prepared to hand over to us. This is what I am asking for.

"What would I do with an apology. I need something tangible," he added.

Cameron was caught making the comment while speaking with the Queen during an event in Buckingham Palace on Tuesday, May 10.

“We had a very successful cabinet meeting this morning. We talked about our anti-corruption summit. We've got...leaders of some fantastically corrupt countries coming to Britain,” he said.

“Nigeria and Afghanistan are possibly two of the most corrupt countries in the world,” he added.

The Nigerian Presidency had earlier responded to Cameron’s comment by saying that he was looking at an old photo of the country.
