An official with Greece’s newly elected Syriza party may have sounded the death knell for a proposed EU-U.S. trade deal that has faced a mountain of opposition from civil society.

The deal is the Transatlantic Trade and Investment Partnership (TTIP), now facing its eighth round of talks between negotiators this week in Brussels.

The TTIP, which would be the biggest trade deal ever, has been criticized as a corporate-friendly deal that threatens food and environmental safety under the guise of “harmonization” of regulations.

Georgios Katrougkalos, now deputy minister for administrative reform, confirmed what he had told EurActiv Greece ahead of his Syriza party’s victory last week: that his parliament would not ratify the trade deal.

“I can ensure you that a Parliament where Syriza holds the majority will never ratify the deal. And this will be a big gift not only to the Greek people but to all the European people,” EurActiv reported Monday.

Because Syriza’s coalition partner also appears to share the anti-TTIP views, EurActiv reports, this means the Greeks could issue a veto, thereby threatening to block the deal.
