An auditor from KPMG will be the fourth witness to take the stand as the corruption trial of former police head Jackie Selebi enters its fifth week.

Dean Friedman is expected to take the stand in the High Court in Johannesburg on Monday.

Friedman compiled a KPMG report into alleged financial irregularities relating to Selebi's lifestyle, as well as an account from where payments were allegedly channelled to his former friend Glenn Agliotti.

Slain mining magnate Brett Kebble and his associate John Stratton allegedly used the bank account of a company called Spring Lights to send Agliotti payments.

Agliotti, a convicted drug trafficker turned State witness, previously testified that he asked Kebble and Stratton for a $1-million "consultancy fee" for access to Selebi.

Friedman's testimony will follow on from Agliotti's, his ex fiance Dianne Muller and her father Martin Flint.

While Agliotti has maintained he never "bribed" Selebi, Muller earlier testified she saw Selebi leave her office with a bank bag she had filled with R110 000 in cash and which Agliotti gave him.

Flint did banking for the Spring Lights company and testified he cashed cheques for Agliotti with stubs marked 'JS', 'chief' and 'c.o.p'.

All three of these witnesses stand to receive indemnity from prosecution on charges ranging from corruption, fraud and theft to money laundering if they testify "honestly and frankly".

Selebi faces a charge of corruption and another of defeating the ends of justice in connection with at least R1.2-million he allegedly received from Agliotti and others in return for favours.
