Animal Welfare (Non-stun Slaughter)

Muslim constituents in Wycombe will want to buy halal meat and they should be able to do that. One of my Muslim constituents wants to buy halal meat because of not only the religious justification, but welfare. For him, halal slaughter is a method with a higher standard of welfare than other methods that were common, such as strangulation. Could an element of the debate be that animal welfare standards have advanced with technology, and that in many cases we can find common ground for animals to be both stunned and halal slaughtered?
