Health Secretary Shona Robison has welcomed an inquiry into mental health services in Tayside after previously being accused of ignoring pleas from grieving Dundee families.
The group claim it has identified at least 10 suicides which could have been prevented had better help been available at the centre.
On Thursday, Scottish Labour leader Richard Leonard challenged First Minister Nicola Sturgeon about the deaths at First Minister’s Questions.
Campaign representative Gillian Murray, whose uncle David Ramsay killed himself after being refused admission to Carseview, also attended.
Ms Robison said: “The chair and chief executive of NHS Tayside want this inquiry to be an opportunity to capture the concerns of the patients and families who have used, or felt let down, by the services.
“People who need mental health services, and their families, should have full confidence that they will receive the highest standards of care when they or their loved ones are in a very vulnerable condition.
“I hope that this inquiry will show that not only are these concerns being listened to, but also that the recommendations of the recent Health Improvement Scotland and Mental Welfare Commission inspection reports are being implemented.”
Ms Robison also had to step in to defend Ms Murray through social media site Twitter on Friday after she received a torrent of online abuse following her appearance at the Scottish Parliament.
The Health Secretary said Ms Murray and her family have “every right” to raise concerns and “shouldn’t be criticised for doing so”.
