Green Party leader Natalie Bennett branded Lib Dems “the lapdogs of corporate Europe” at the weekend over their support for the transatlantic trade deal.

She warned a free trade deal between the US and European Union would “blow apart the power of our democratic decision making” at her party’s spring conference in Liverpool on Saturday.

The EU Commission labelled the Transatlantic Trade and Investment Partnership (TTIP) “the biggest trade deal in the world” and claimed cutting regulation would boost the EU economy by £120 billion.
