The Irish government has promised to "call out" British ministers if legislation addressing Northern Ireland's decades of violence is unfair or unbalanced.
Tánaiste Simon Coveney said the political debate at Westminster around the Troubles was one-sided.
"Legacy is complicated and difficult, and in some way the debate is somewhat one-sided, and that poses huge dangers and creates real concerns amongst the nationalist community in particular because of the lack of a voice to create balance in that debate in Westminster," he said.
"Whatever way you describe it, there is not a balanced debate on this issue and the secretary of state faces real challenges in ensuring that we have legislation that is fully balanced and fair, and takes into account the sides equally in terms of the balance of that legislation."
Secretary of State Karen Bradley faced fierce criticism recently after she said killings at the hands of the security forces were "not crimes". She later apologised.
Mr Coveney said: "She knows that she made a real mistake but now she wants to move on in a balanced and fair way.
"I think Karen Bradley is a good person and I can work with her, so if the legislation moves in the wrong direction we will call that out, we have an obligation to do that."
