Oh, and the young ambitious government whip who forced through Maastricht?

David Davis

My personal view is EU+UK would have developed a close and, more importantly, sustainable relationship

In substance, single market and customs union

But allowing EU to integrate just as it wished (Schengen, Eurozone, etc) with no UK role

But Maastricht really was the last time such an association agreement could have been done practically

After that, too late, and not worth the cost and effort
