The father of honeymoon murder victim Anni Dewani has called on a coroner to compel her husband to give evidence at her inquest.
Vinod Hindocha said he felt Shrien Dewani "owes" the family answers over her death because he did not give evidence during his trial in South Africa.
Millionaire businessman Mr Dewani was cleared of orchestrating the killing of his new bride Mrs Dewani, 28, who was fatally shot in a car-jacking as the couple drove through the outskirts of Cape Town on November 14 2010.
The 34-year-old returned to England without commenting in public after Cape Town Judge Jeanette Traverso dismissed the case against him, describing evidence from a key prosecution witness as being ''riddled with contradictions''.
A North London coroner could rule on whether Mr Dewani will appear at her inquest and Mr Hindocha, 59, said he hoped to question him.
He told Sky News: "There are still so many questions we want to ask Shrien and we hope he will be man enough to answer them.
"Why did he marry Anni if he is gay, why did he take her to South Africa on honeymoon, why did he leave her alone to die?
"We just want answers, so we can begin the mourning process. Shrien owes us that."
Mr Dewani has always denied hiring a hitman to kill the Swedish engineer, and told police he escaped from the window of the cab minutes before she was shot.
Mrs Dewani's body was found in the back of a taxi in a rough township.
Three men - Zola Tongo, Mziwamadoda Qwabe and Xolile Mngeni - were given jail terms for their role in the killing. They claimed Mr Dewani arranged a hijacking-gone-wrong in which he would survive while his wife was killed.
