Weight watchers on the NHS?

I was at Westminster today at the All Party Parliamentary Group on Obesity meeting. One of the speakers was from Weight Watchers. She described how they are working with some GP's And PCT's to help people lose weight. While they can be very effective I did raise concerns (from my own experience I may add!) that they sometimes used high pressure sales techniques at the meeting to sell expensive weight watcher merchandise such as special scales, spoons, recipe books, magasines and some very dubious processed foods. I would like some reassurance that doesn't still happen.

For the record: I did successfully lose weight with weight watchers and have managed to keep it off with out needing their branded goods.
