Figures show the number of patients in Wales waiting longer than 36 weeks has risen sharply.
7,611 patients waiting for that length of time in April, a rise of more than 2,000 on the previous month, according to Statistics Wales figures.
"Instead of getting better, NHS waiting times are getting progressively worse" says Shadow Health Minister Darren Millar.
“Spiralling waits for treatment are now so common-place that they have almost become the norm. That’s absolutely unacceptable."
“April’s rise came at a time when financial pressures were at an all-time high and it’s clear that Labour’s record-breaking budget cuts continue to have an incredibly damaging impact"
“The Welsh Labour Government’s target is already less ambitious than in England, yet these targets are still frequently missed" said Welsh Liberal Democrats leader Kirsty Williams.
"Why should Welsh patients be forced to wait so much longer?"
