Chris Cairns' wife has been accused of lying to the court to support her husband.
Mel Cairns told the jury in the former cricket player's perjury trial that she would never lie to help her husband, "especially, I would never lie in a court of law".
Under cross-examination by Crown prosecutor Sasha Wass QC it was put to Ms Cairns that she loves her husband very much and was prepared to go to great lengths to protect him.
Referring to a witness statement Ms Cairns had given during Cairns' successful libel trial against Lalit Modi in 2012 in which she said "Chris told me on occasions Modi's libels are down-right lies - I want to believe him and I want the world to believe him", Ms Wass suggested that the reality is Ms Cairns wants to help her husband so much "you would lie to help him", adding that she had a motive to mislead.
"Do you have a motive to lie for your husband?"
Ms Cairns replied, "I have no motive to lie, I have no reason".
She gave evidence via video link from Canberra, where she and Cairns live with their two children, but said she would much rather be doing so in person at the court in London.
"It broke my heart to watch Chris walk every day alone to and from court and knowing he was going home alone."
She said the couple are not in a financial position for her to be able to afford to travel to the UK.
During his evidence, Chris Cairns disclosed during cross-examination that his relationship with Ms Cairns had begun before his relationship with his first wife Carin had ended adding, "I didn't tell anybody".
Ms Cairns was grilled about their relationship - how serious it got and how fast.
In a witness statement Ms Cairns gave in 2012 for Cairns' trial against Mr Modi she said she first visited Dubai with Cairns in April or May 2008.
She was then forced to correct her statement saying instead that the couple travelled to Dubai in July 2008.
Upon the change of statement Ms Wass suggested, "isn't it a case of Mr Cairns telling the jury yesterday that you did not visit in April-May and now you're changing your account to match his?"
Ms Cairns disagreed, saying she made a mistake but she was giving evidence four years after the fact - "I am now sure it was in July".
As to why she didn't disclose her mistake in court off her own bat she said, "perhaps I should have thought about raising it again".
Ms Cairns was asked about an interview she did with a women's magazine in which a three-month trip to Europe with Cairns in June 2008 was likened to "a honeymoon for us".
She defended the suggestion their relationship was so advanced so early on saying that in newspaper articles, "they often want things to sound lovey or fairy or fluffy" and that she was referring to it being more like a honeymoon period, a new love.
Ms Cairns' evidence ended with two questions from the defence. To the suggestion she not only lied to help her husband but that she was part of the match-fixing business, Ms Cairns replied "absolutely not".
To the suggestion that she knew the diamond traders Cairns was working for in Dubai were in fact his match-fixing paymasters she said "I wouldn't believe it".
