Shadow justice secretary Liam Kerr said the legislation, as it currently stands, is “a Victims’ Bill in name only”, which fails to deliver the change that victims of crime “need and deserve”.

Among the key amendments the party want to see are the following:

• Initiating an inquiry into grooming gangs in Scotland
• Ensuring victims are always informed if a decision is taken not to prosecute someone
• Informing all victims when plea deals are struck between defence and prosecution lawyers
• Requiring victim statements to be read out in court, by victims themselves if they choose
• Ensuring a real Suzanne’s Law, that would mean “no body, no release”

Mr Kerr said: “Parliament has the chance to reboot Scotland’s justice system so that it finally gives crime victims the rights they need and deserve. But the SNP bill, as it currently stands, fails to deliver that, so we can’t vote for it.

“At the moment, it’s a Victims’ Bill in name only – a wasted opportunity. The Scottish Conservatives have submitted several common-sense amendments to strengthen this bill and deliver the real change that victims’ groups demand.

“I’m pleased that the SNP have backed our calls to scrap the not proven verdict and have heeded our opposition to their juryless trials plan – but now they must go further. I urge the Nationalists to accept our amendments, instead of selling victims short.”

Speaking ahead of the final vote, Justice Secretary Angela Constance said: “This landmark bill, if passed by Parliament, will transform the experiences of victims and witnesses within Scotland’s justice system. Victims will be heard, supported, protected and treated with compassion, while the rights of the accused will continue to be safeguarded.

“Key reforms include abolishing Scotland’s historic ‘not proven’ verdict for a clearer, fairer and more transparent decision-making process. There will also be wholesale reform to the management of sexual offence cases as we know these victims in particular, who are mostly women and girls, can be re-traumatised by the current system.

“This legislation was shaped by the voices of victims, survivors and their families who have campaigned long and hard for further change. Parliament must stand with them and help ensure the justice system doesn’t just respond to crime but helps those who have been harmed to rebuild their lives.”
