Pembrokeshire council has approved a 12.5% rise in council tax.
It will be the first double-digit increase in the tax agreed by a Welsh council since 2004. The increase comes as the council seeks to plug a £16m funding gap, but the authority says it still has the lowest tax in Wales.
Cabinet members voted by 40 to 18 to approve the council tax rise.
Bob Kilmister, Cabinet member for Finance said the result was "good news" for the council to "make the changes" it needs.
