Trade negotiations with the European Union are down to the wire.

The Prime Minister is in Brussels with an aim to conclude talks over a free trade deal with the EU which have continued for roughly for years.

A senior political reporter travelling with the delegation says the European negotiators are running down the clock until the very last minute.

The Herald's Thomas Coughlan told Heather du Plessis-Allan Jacinda Ardern's made it clear she's willing to walk away without a deal.

“That is possibly a negotiating strategy, a signal to the Europeans that if they don't come to the table, she's going to walk from the table. It is possible that we could see a last-minute deal announced.”
