Ghana has been ranked the fifth democracy in Africa, president John Mahama has announced.

President Mahama made the announcement on his Facebook page after participating in an anti-corruption summit in the UK.

"I am happy to inform you that we are now, officially, the fifth democracy in Africa. In the prestigious Democracy Index 2015, we were ranked 53rd in the world, a leap of no less than 15 places since 2014," president Mahama wrote.

President Mahama said this "significant leap offers others inspiration and hope."

He said the success of "our democracy" will be doubled "by our success in the fight against corruption."

He added that government will continue improve democratic practices in Ghana.

"For me, it is of paramount importance that we move forward Ghana’s anti-corruption agenda as contained in the National Anti-Corruption Action Plan (2015-2024) and our commitments under the UN Convention against Corruption (UNCAC)," he said

"Our hard work, our vision and dedication earned us a well-deserved place in the community of nations. Let us all keep moving forward and upwards!"
