Nor was it much of a shock that the interviewer did nothing to intervene - if nothing else than to get Prescott for once in his miserable political life to stick to the point, but merely apologised vaguely afterwards I assume for his own conduct by saying that sometimes it's best for these things to be allowed to run their natural course - without getting involved.
As to the issue being discussed - Labour's (Prescott's, in fact) appalling record on housing and the disastrous assault on our nation's green spaces under that regime, which, Prescott seemed quite happy to admit, was more or less a conscious brand of class war - others will disagree no doubt, but I thought Goldsmith wiped the floor with Lord Two Jags (or should that be Lord Two Shags?).
Goldsmith commanded his brief and, when permitted by the lame BBC interviewer, delivered a rational, compelling set of reasons for why, to meet the housing shortage, existing housing stock must be renovated, only appropriate spaces should be built on (ie: not greenfield sites), and local councils must be released from central government meddling so they can do what they were elected to do and make policy to suit the area for which they are responsible and which they (in theory) know best how to manage.
It was a polished performance and Prescott had no answer to it, his policies having buggered everything up (to borrow his expression) in the first place.
One-nil to Goldsmith.
(And minus one to the BBC, again.)
