Parky works over-time on unemployment

Postscript to my story yesterday about Lord Parkinson's spot that unemployment has been higher at the end of every Labour government than it was when each one came to power.
The former Tory Trade Secretary's statistic got lots of coverage at the time, and at a cabinet meeting shortly after his proclamation, Parkinson tells how he was taken aside by Michael Heseltine (as was).
"Is that stuff about Labour and unemployment really true?" he asked.
"It was at that point that I knew the challenge I had to persuade voters," Parkinson recalls. "I couldn't even convince my own cabinet I was right."
