Just when President Muhammadu Buhari is airborne to the United Kingdom, the Prime Minister of Britain, Mr. David Cameron was caught on camera telling Queen Elizabeth that leaders of some “fantastically corrupt” countries, including Nigeria and Afghanistan, were due to attend his anti-corruption summit.

Cameron will host an international anti-corruption summit on Thursday aimed at stepping up global action to combat corruption in all walks of life. He was talking with the queen about the summit in a meeting captured in a pooled video feed made available to the ITN broadcaster and published by Reuters.

“We had a very successful cabinet meeting this morning, talking about our anti-corruption summit,” Cameron said when the queen approached. “We have got the Nigerians – actually we have got some leaders of some fantastically corrupt countries coming to Britain.”

“Nigeria and Afghanistan – possibly two of the most corrupt countries in the world.”

The queen did not respond to Cameron’s comment, even as the Archbishop of Canterbury, Justin Welby chipped in that “But this particular president is actually not corrupt.”

Some of the world dignitaries expected at the meeting, which will also have acting Chairman of the EFCC, Ibrahim Magu, in attendance, include: US secretary of state, John Kerry; Managing director of the International Monetary Fund, IMF, Christine Lagarde; and World Bank president, Jim Yong Kim.

Afghanistan is at number 166, second-from-bottom, in the latest ranking of countries by the campaign group Transparency International’s Corruption Perceptions Index,while Nigeria is at number 136 in the index.
