The Guardian view on post-Brexit trade: only hard choices are left | Editorial

Boris Johnson likes to pretend that free-trade deals are easy and have no downside. Talks with Australia are proving him wrong

There is agreement across the Conservative party that free trade is a good thing, in theory. Unity is harder to sustain over practical detail, as has become clear through negotiations on a deal with Australia.

The agreement has immense symbolic value. It would be the first substantial post-Brexit deal that was not a rollover of terms that were available under EU membership. The prime minister sees it as the enactment of his global Britain" rhetoric. The government is determined to have such a trophy ready in time for next month's G7 summit.
