Praveen Halappanavar has said he has received a number of abusive letters since his wife Savita's death at Galway University Hospital last October.

Mr Halappanavar was speaking to Miriam O'Callaghan on RTÉ's John Murray Show after his lawyers said they will issue proceedings against the HSE for alleged negligence in the death of Mrs Halappanavar.

He said: "Even I have been receiving abusive letters ... from different campaigners. There is one particular campaigner that keeps writing again and again.

"Basically, I was told to leave the country. I was told to clean the mess that our country [India] has, rather than cleaning the mess here and to leave stuff for them to clean and mind my own business. It's hurting."

He said that legal proceedings were the only option left to the family as they seek to find out why Mrs Halappanavar died.

Mr Halappanavar said he is determined to get to the "bottom of the truth" about what happened.

He said: "It's a family decision. Savita's father and the whole family is very angry. They want to take legal proceedings against the hospital.

"You are not getting to the truth and the HSE report is nowhere near to it.

"We did push for a public inquiry, which never happened, so we see this as the only option left to us at the minute.

"I have the terms of reference for the HIQA report and it audits the facility and the capability of the hospital.

"The way I put it in short is: 'Tell me the truth and it will all be over'. There are some midwives who never attended the inquest and it still bothers me."

Mr Halappanavar plans to meet Minister for Health James Reilly for a third time next week and said there are plans to go to the European Court of Human Rights if a public inquiry is not forthcoming.

He said he will tell Minister Reilly that the HSE's clinical review was a "whitewash" and that it revealed no new information about how his wife died.

Mr Halappanavar said: "All we are here for is to get to the bottom of the truth. The whole family wants that no woman has to go through the same pain that Savita had to go through or no family go through the circumstances that we had to face.

"We are going through the European Court of Human Rights, which we are planning ... if there is no public inquiry, that's the next step.

"We want to get to the bottom of the truth and somebody has to take the responsibility for the cause."

Mr Halappanavar said he is still finding it very tough to cope with his wife's death, but he has kept himself busy by continuing to work, and praying and meditating regularly.
