In yesterday's debate on the timetable for discussing the Government's anti-terror legislation, it was asserted (by Ken Clarke) that the amount of time being spent on scrutinising legislation in general was decreasing.
TheyWorkForYou is probably in a position to have a stab at calculating the amount of time spent on a given legislative proposal. It'd be a nice addition to that site, and allow comparison with specimens of legislation enacted by Parliament under previous governments.
