NEW ZEALAND doctors joined trade unionists yesterday to refute PM John Key’s claims that mass opposition to a shady free trade deal was “misinformed.”

Tens of thousands of people took to the streets across the country against the secretive Trans-Pacific Partnership (TPP) at the weekend — but the National Party leader has dismissed them as “rent-a-crowd.”

Mr Key said protesters’ objections were manageable and they should wait until they see the deal.
