Tory plans to scrap human rights legislation are "dangerous" and would inflict "immense damage" on the UK's international reputation, according to the legal affairs minister.

Roseanna Cunningham said the controversial proposals were evidence that Prime Minister David Cameron and his colleagues were "running scared of Ukip".

The Scottish Government strongly opposes the Conservative plans to replace the Human Rights Act, which enshrines the European Convention on Human Rights in British law, with a British Bill of Rights if elected in 2015.

In order to be implemented in Scotland, the move would require the consent of the Scottish Parliament and Ms Cunningham called on MSPs of all parties to make clear that consent would not be given.

Speaking at Holyrood, Ms Cunningham said: "David Cameron and (UK Justice Secretary) Chris Grayling are running scared of Ukip and pandering to the europhobic extremists in their own party.

"These are dangerous proposals which threaten the rights all of us enjoy. If they were ever implemented they would inflict immense damage on both the UK's international reputation and on international efforts to protect and secure human rights around the world."

Ms Cunningham referred to a landmark Glasgow case in which a woman with multiple sclerosis won a ruling that the decision to cut her welfare benefits under the so-called "bedroom tax" breached her human rights.

She said: "It does sound very much like an excuse for depriving the most vulnerable people in society of hard, enforceable rights."
