Reform of Scotland's justice system is vital to restoring public confidence, the minister responsible has said.

Speaking ahead of a parliamentary debate on the issue, Cathy Jamieson argued that the six-month review of legal aid would be a step towards a more efficient service.

"Public perception of legal aid is mixed," she said. "For many people the system works well and allows them to get the help they need.

"However, some people view the system with confusion, at worst with mistrust. Hard-working people who find themselves in civil cases do not always find it easy to get the legal help and advice they require."

"I will urge parliament and everyone with a stake in this issue to accept the challenges that face legal aid services in Scotland," she added.

"Legal aid is a cornerstone of our justice system. But justice is not served if people cannot find the right legal advice."

The justice minister highlighted the rising costs of legal aid over the past 10 years.

The budget totals up to £150 million a year, two thirds of which is spent on criminal legal aid.

"We can, with improvements, make better use of that budget," Jamieson insisted.

"However, the real prize is a legal aid system that is fair, transparent and efficient, better meeting the needs of Scotland's citizens."

The Scottish Legal Aid Board described the review of services as a "great opportunity" for reform.

"Holding a high profile debate today highlights to the public the importance of extending access to justice and provides a valuable opportunity for discussing how best this can be achieved," said chairman Jean Couper.

"Legal aid is an important public service for many people who do not have the financial resources to assert their legal rights. We strongly support the justice minister's plans."
