The prosecution’s case portrayed a sustained pattern of alleged corruption.

The long-awaited moment of reckoning has arrived at Southwark Crown Court.

After a gruelling four-month trial that exposed what prosecutors described as the systemic corruption at the heart of Nigeria’s oil sector, the jury has retired to deliberate on the fate of former Petroleum Resources Minister, Diezani Alison-Madueke.

For years, ordinary Nigerians have watched as vast public wealth allegedly disappeared into the hands of a ruling elite, while infrastructure and public services deteriorated.

In London, prosecutors say that image of public service has been thoroughly dismantled.
