Mismanagement of the health service over the past nine years is catching up with the SNP, according to Scottish Liberal Democrats leader Willie Rennie. The attack comes as Nicola Sturgeon prepares to reveal her party's "bold, ambitious and reforming" manifesto in Edinburgh on Wednesday. The SNP manifesto will include a commitment to "record NHS funding" of £500m above the rate of inflation. Rennie said: "Under the SNP, too many healthcare issues have been allowed to drift down the agenda. Their record on ignoring the pressures facing the NHS over the past nine years has started to catch up with them." He added: "Enough is enough. Our programme for Scotland offer a bold and positive alternative to the SNP's slumber." The Scottish Liberal Democrats' plans for the NHS include increasing the share of the NHS budget allocated to GPs and mental health services, trebling the primary care fund and doubling the funding for children and adolescent mental health services (CAMHS). Speaking ahead of a campaign event in Morningside, Edinburgh, Rennie claimed Scotland had been "waiting almost a decade for the SNP to make the transformational change in our public services that would make them the best in the world again". He added: "Some children have already been waiting a year for mental health treatment. They cannot wait on the SNP to deliver the step change that's so desperately needed." As she prepares to lay out her party's manifesto at a huge Edinburgh launch, Nicola Sturgeon is expected to say the SNP have "achieved a huge amount" since 2007. She will add: "Scotland is a better country today as a result." The manifesto will commit a re-elected SNP government to an increase in health funding of "£500m more than inflation" by the end of the next parliament, as part of a package of investment and reform. On the NHS, the First Minister is expected to say: "This pledge of above inflation investment is a clear sign of our commitment to our most cherished public service. "But we all know that more investment in the NHS is not enough - to make our NHS truly fit for the future, we also need to change the way it delivers services. "That is why we will also use the opportunity of record NHS funding to shift more resources into social care - just as we have done this year, we will transfer funding each year from the NHS to integrated health and social care partnerships to help keep people out of hospital. "We will also ensure that more of the NHS budget is spent on primary and community care and on mental health. "And we will invest in new elective treatment centres to deal with the growing demand for routine operations that comes with an ageing population. She will add SNP health plans are just "one example of the transformation at the heart of our manifesto". Responding directly to Willie Rennie's comments, an SNP spokesperson said: "Under the SNP, Scotland's NHS funding funding has risen to record levels, as has the record number of doctors, nurses and midwives - with more than 11,000 staff more than when Willie Rennie's party were in office. "Our manifesto commits us to increasing the NHS revenue budget even further, by £500m more than inflation by the end of this parliament - which means that it will increase by almost £2bn in total.  "We will also implement a new £100m cancer plan, further increase GP numbers and create an extra 1,000 training places for nurses and midwives. "The NHS is the jewel in the crown of Scotland's public services and it will always be in safe hands with the SNP." Scottish Labour cast doubt over how the SNP health promises would protect vital local services. The party's public services spokeswoman Jackie Baillie said: "The SNP claim they will invest more in the NHS but refuse to guarantee that services like emergency care at the Vale of Leven and the children's ward at St John's Hospital in Livingston will be protected. "Thousands of parents and children depend on the help and support they get from their local hospitals, yet the SNP won't give them the assurances they need." Baillie added: "We have been very clear - Labour will protect local NHS services." The Scottish Greens called for a "joined-up approach" to the health service. Health spokeswoman Alison Johnstone said: "By improving pay and conditions for social care staff and increasing the carer's allowance we can provide better care settings at home to prevent delayed discharges in our hospitals. "And by prioritising resources and recruitment for GPs we can help prevent the need for more acute services." She added: "Successive Labour and SNP-led governments have not been bold enough on preventative spending, whereas it is a consistent Scottish Greens priority. "We have led the way on making energy efficient housing a national infrastructure priority as cold homes have a huge impact on health, and we have kept the pressure on ministers to increase spending on cycling and walking to make healthier lifestyles easier for all. "The challenges our NHS continues to face, around inequality and an ageing population, can be tackled with Green policies. "With our proposal to reform income tax so everyone earning less than £26,500 keeps more of their pay, we can raise over £300m in additional revenue to invest in a healthier Scotland." The Scottish Conservatives have said Scotland "deserves better" from the SNP on health. Health spokesman Jackson Carlaw said: "Nicola Sturgeon must use this manifesto to show that she is focused on being a First Minister for Scotland and not just on spinning for the SNP. "Over the last five years, the record demonstrates that the SNP failed to pass onto Scotland's NHS anything like the full spending increase seen down south, so people should be very wary of similar SNP spending promises now. "As a strong opposition, the Scottish Conservatives will insist that an SNP Government rises to the challenge both to ensure our NHS is able to cope with rising demand and also to ensure it does far more to meet its promises, so that all patients get the high quality care they deserve."
