I don't think it's a good idea for Parliament to control, fix and set retail prices. I think it really opens up a can of worms. It's a dangerous road to take.
In France, and I think to a certain extent Minister Champagne is inspired by France, they actually set up a guideline for 5,000 grocery products. It wasn't about price setting. It was more a guideline for industry. The discussions included manufacturing. Actually, France in fact started with manufacturing before going with retailers.
