“We need to go into any deal with our eyes wide open and to be fully aware of the risks and cost as well as the potential benefits and the likelihood of achieving those benefits. So we have a slightly one-sided picture of what we do get from the TPPA,” he said.

“For people to say that we can pull out of this TPPA after six months of being in it is very deceptive. That is not the way the world works and is a very naive assumption. Say if somebody here doesn’t swim we cannot throw him into the deep end of the pool and say he will learn how to swim,” he added.
