There's no guarantee Jacinda Ardern will come home from this week's visit to Europe with a free trade agreement with the EU.

The Prime Minister is pushing the deal during meetings with European leaders.

She's received support from Spanish President Pedro Sánchez‌ during a meeting in Madrid overnight, but other EU members are more reluctant to sign an FTA.

Reporter Thomas Coughlan is travelling with the PM and told Mike Hosking she isn't taking an FTA for granted, and won't want to sign up to a sub-par agreement.

“She might get on the plane to Australia at the end of this week without a deal, there’s certainly a chance if the Europeans don’t move and in particular, if they don’t move on agriculture.”

Ardern and Sánchez‌ have also announced an expansion to New Zealand's working holiday agreement.
