This Saturday sees the latest demonstration by supporters of the Salmon Farm Protest Group - which has recently formed a limited company to pursue its aims, according to material sent out last week. This time, only supermarkets in Edinburgh will be targeted. However, campaigners will also target stores in Dublin during next week and in London on December 21.

Campaign leader Bruce Sandison confirmed that the group will be handing out free Alaskan salmon to shoppers - but declined to tell IntraFish what form this would take.
