How much does Prezza weigh?

The Lib Dems proposed a 'freedom bill' yesterday to cut back on legislation

Best fact is that the 114,366 pages of every act and statutory instrument passed since '97 - without bindings mind - weigh more than 36 stone - more than the combined weight of two John Prescotts.

I hoped the Lib Dem press office had somehow lured the DPM onto a set of scales, but according to the footnotes they used "telephone-based research service Any Question Answered".
