More than 28,500 people have signed the petition on the 38 Degrees website urging Fiona Hyslop, the Scottish Cabinet Secretary for Europe and External Affairs and member of the ruling Scottish National Party, to make sure that the SNP "takes a tougher stand against TTIP."
Scotland’s Stop TTIP Today campaign website said the petition will be submitted to the Scottish government on Tuesday afternoon.
Another petition urging the European Union to stop the TTIP agreement has meanwhile gathered more than 3 million signatures on the petition website.
The secretive deal has drawn widespread criticism for its potential to lower environmental, health, safety, and workers’ rights standards, as well as for enabling the extra-judicial settlement of disputes in circumvention of national sovereignty.
