A group of artists including actors Ruth Wilson, Andrew Scott and Juliet Stevenson and designer Vivienne Westwood are fronting a campaign to raise public awareness of the trade deal TTIP (pronounced tee-tip) which is being secretly negotiated between the EU and the US. They are questioning its democratic validity, as no UK MP has had access to the negotiating documents. This week a European petition against TTIP has reached a record 2 million signatures, a few days ahead of a crucial vote on the deal by MEPs in the European parliament.
