Peters says the deal was neither free, nor fair.

Analysis - Winston Peters' opposition to the India free trade deal has turned what could have been a huge win for the prime minister into a complex political scrap.

The Trade Minister says he's confident the Free Trade Agreement with India will be implemented despite New Zealand First's opposition, saying he'd be surprised if Labour didn't support it.
