UK Prime Minister David Cameron has described Nigeria and Afghanistan as "fantastically corrupt" countries in a conversation with the Queen.
In a video circulated through the world's media, Cameron could be seen speaking to the Queen, Archbishop of Canterbury Justin Welby and Speaker Justin Welby. They were at Buckingham Palace at an event to mark the Queen's 90th birthday.
They were speaking about an anti-corruption summit in London.
"We've got some leaders of some fantastically corrupt countries coming to Britain... Nigeria and Afghanistan, possibly the two most corrupt countries in the world," Cameron said.
While the Archbishop of Canterbury jumped to Nigeria's current president Muhammadu Buhari's defence, stating “but this particular president is not corrupt... he's trying very hard.”
The two countries are known to be plagued with corruption issues – in the 2015 Transparency International report, Nigeria was ranked at 136, and Afghanistan at 167 out of 168 countries, though many countries sharing ranked places.
When Muhammadu Buhari was sworn in as president of Nigeria he vowed to fight corruption during his campaign, which remained rampant under his predecessor Goodluck Jonathan.
Transparency International reports corruption hits hardest at the poor in Nigeria who make up more than 40 per cent of the 179 million people.
While in Afghanistan millions of dollars that should have gone on reconstruction have been reportedly wasted or stolen, seriously undermining efforts to sustain peace.
The UK is hosting world and business leaders at an anti-corruption summit on Thursday in London, with the aim to secure a new global commitment to expose, punish and drive out corruption in all walks of life.
The UK Government website says Cameron wants all those at the summit to sign up to the first ever global declaration against corruption that would commit them to working together to tackle it, acknowledging that corruption undermines efforts to end poverty, promote prosperity and defeat terrorism and extremism.
