You won't have seen it on any national news channel, so here's the leaked footage of Andrew Lansley being chased by protesters down the corridors of the Royal Free Hospital.

The voice you can hear is that of Dr Ron Singer, a retired GP who is currently president of The Medical Practitioners' Union. "Nobody understands your bill," he cries, adding that "it's got a thousand amendments because it was so poorly drafted", a charge that Downing Street would no doubt second.

Also visible from 14 seconds onwards is June Hautot, the woman who so memorably berated the Health Secretary last month.
