Indonesia's anti-corruption commission says it plans to reveal a tape recording of the country's Agriculture Minister talking to a man accused of taking bribes over beef imports.
The Corruption Eradication Commission, or KPK, won't say what the recording is about, but plans to play it in court as evidence about bribes allegedly paid over beef quotas.
Indonesia has restricted beef imports by about 80 per cent since 2010.
The country's biggest importer, which brings stock from Australia and the US, is accused of paying bribes to get a better allocation.
It is alleged the Chairman of the Prosperous Party, Luthfi Hasan Ishaaq, pocketed $100,000.
Indonesian Agriculture Minister Suswono has not been named a suspect in the scandal, and has denied talking to Mr Luthfi about it.
The anti-corruption commission says it will summons Mr Suswono, who is from the same party, to give evidence next week.
The KPK says it has a recording of the pair speaking but will wait to reveal the contents of the discussion in court.
