FORMER Australian prime minister Malcolm Turnbull has issued a warning to the UK Government over their plans for post-Brexit trade with the EU.

Boris Johnson has long been relaxed about the idea of having a so-called “Australia-style” deal with the bloc after December 31 if a full trade agreement is not reached.

Turnbull was this week quick to point out that there is no trade deal between Australia and the EU – meaning there are “large barriers” to trade.

Australia and the EU do business on World Trade Organisation rules, but they have a few specific arrangements in place. The country does not do as much trade with the bloc as the UK.

This morning Johnson and EU Commission president Ursula von der Leyen warned a No-Deal exit is looking more likely all the time.

Earlier this week the pair decided they would give it until Sunday to reach an agreement.

Speaking to Question Time last night, Turnbull was clear that the “Australia-style” arrangements aren’t ideal.

He said: "Australia has a deal with the EU on WTO terms and there are really some very large barriers to Australian trade with Europe, which we are seeking to address as we negotiate a free trade agreement with Europe

"But Australians would not regard our trade relationship with Europe as being a satisfactory one.

"There are very big barriers to Australian exports of agriculture products in particular and a lot of friction in the system in terms of services.”

Turnbull represented the centre-right Liberal Party and led the country from 2015-2018.
