Tories offer prime cuts in business rates for small firms
Supermarkets and other big businesses could face higher business rates under a Welsh Conservative government, with a tax cut for smaller companies.
The Tories propose changing how rates are calculated, as part of a pledge to put the needs of small businesses at the "heart of the Welsh government".
Retailers warned against "creating winners or losers or more complexity".
But Welsh Tory leader Andrew RT Davies - visiting a Newport butcher - said the vast majority of Welsh firms were classified as small and they had suffered "tough times".
