John McAreavey, whose wife Michaela was murdered on honeymoon in Mauritius, has said he will never give up trying to ensure whoever killed her is caught and convicted.
Speaking ahead of the 10th anniversary of her death, Mr McAreavey said he felt a sense of personal "failure".
No-one has been convicted of the murder of Mrs McAreavey.
The 27-year-old was the daughter of former Tyrone Gaelic football manager Mickey Harte.
The young teacher was strangled to death at a luxury hotel in northern Mauritius 12 days after her wedding in County Tyrone.
In an interview with BBC News NI, Mr McAreavey said: "To be here in this situation 10 years later, not having the justice delivered for Michaela is a hugely difficult and frustrating thing.
"I guess for me it probably feels like a failure, and I know that obviously I can't deliver this (on my own), but it does sort of give me a sense of failure that I haven't been able to close this chapter out and to deliver the justice that is the very least of which Michaela deserves."
