A woman widowed by a fishing boat tragedy will travel to London to complain about the release of a report which she said is vital to the case.
The Peterhad boat Trident went down off Wick in 1974 with the loss of seven men.
An inquiry is probing the sinking, but relatives learned last week of a 1976 report which found the vessel had insufficient stability.
Jeannie Ritchie said she now wants to meet her MP and the transport minister.
The Advocate General's office earlier said the report was public and no attempt was made to withhold it.
An inquiry held a year after the sinking found the Trident had been struck by a massive wave, but many of the relatives insist the vessel was unstable.
A new investigation was ordered when the wreck was discovered by amateur divers in 2001.
The fresh inquiry began in Aberdeen last October, but was adjourned earlier this year. It resumed on Tuesday.
All the crew on board - Robert Cordiner, Alexander Ritchie, George Nicol, James Tait, Thomas Thain, Alexander Mair and Alexander Summers - were lost when the Trident sank.
