“It meant we couldn’t really engage in the cam ign on that enlivening issue.
“We didn’t have much option but to keep trying to crux back to the economic risks.”
Lord Cooper also explained that the Abide cam ign back-tracked on a number of claims they made.

“Secondly it sounded strangely specific.
“The figure was sort of humanely phased out because we inaugurate when we tested the reaction in focus groups, we found people precisely rejected it.
“They didn’t believe it.”
