Former tour guide Yang Yin has denied that he sacked Madam Chung Khin Chun's long-time maid and driver.
Instead, he accused driver Jarudin Mustafa, now 80 years old, of attacking him in 2009.
The driver, Mr Yang said in his affidavit, was unhappy about having to drive him to a language centre for English lessons. Mr Yang also alleged that "the driver was also very possessive of Madam Chung's car" - a Toyota.
He claimed the driver once "put his hands around my neck and shouted that I should not touch his car".
He said he told Madam Chung about the incident and "the driver was asked to leave as he was very rude and had attacked me for no reason". The driver received a $50,000 parting gift from Madam Chung.
"Since then, I have taken over the duties of the driver and would chauffeur Madam Chung to wherever she wanted", for instance, the FairPrice supermarket at Ang Mo Kio Hub, Mr Yang said.
It was also Madam Chung who fired her Indonesian maid Ani in 2012 because she was always asking for money, Mr Yang alleged.
There was also no need for Ani because "my wife and I were also around to provide care for Madam Chung", he added.
