Dewani trial: Middleman's testimony under scrutiny
Monde Mbolombo says he took on the role of ensuring the hit went off as planned because he wanted to get paid.
The defence has accused Mbolombo of being an outright liar.
He is the state's latest witness in its case against Shrien Dewani, who is accused of ordering a hit on his wife, Anni, during their honeymoon in Cape Town in November 2010.
Dewani has denied masterminding his wife's murder.
The Briton has also pleaded not guilty to five charges, including one of murder.
During cross-examination, the former hotel receptionist said he was becoming confused and tired and needed a break.

It later emerged that he broke down during the adjournment.
Regarded as the middleman in the alleged murder plot, he says he took on the role of ensuring the hit went off as planned because he wanted to get paid.
But in the same breath, he told the court, he wasn't in charge, neither was he acting on anyone else's behalf when he assumed this role.
In a statement Mbolombo made in September, he said he'd suggested Zola Tongo give hitmen Mziwamadoda Qwabe and late Xolile Mgeni, R9,000 of the R15,000 hit money and that he should keep R1,000 for himself.
This is contradictory to what he said in 2012 during Mngeni's trial that he was not expecting anything because it was blood money.
He told the court he did this because he wanted to protect himself and feared prosecution.
