Nigeria's finance minister has resigned over allegations she used a forged certificate to avoid the country's mandatory one-year youth service scheme.
Kemi Adeosun, who lived in the UK until she was 34, said she had been told she was exempt because she was over 30.
Ms Adeosun's resignation follows months of speculation in local media about whether her National Youth Service Corps certificate was genuine.
"This has come as a shock to me and I believe that in line with this administration's focus on integrity, I must do the honourable thing and resign," she said.
Nigerian graduates are not eligible for government work or many private jobs until they have completed the mandatory year of service.
