Ghana's special anti-corruption prosecutor has quit, accusing President Nana Akufo-Addo of "political interference" over a report into a controversial gold royalties deal.
The move comes just three weeks ahead of a presidential election that sees Akufo-Addo facing a tight race against former leader John Mahama.
Former attorney general Martin Amidu announced his resignation late on Monday, saying he had become convinced "that I was not intended to exercise any independence" in the job.
"You had laboured under the mistaken belief that I could hold the Office of the Special Prosecutor as your poodle," Amidu wrote in a letter to the president.
Amidu was appointed by Akufo-Addo in 2018, sparking hopes that he could help curb graft in the country.
