My studies indicate that single/two party states that hoard forex and focus on growth through exports via government backed for profit corporations have done the best economically over the last 50 years. Britain has done nothing but lose geopolitical and economic power over the last 50 years. Britain is a poor role model to follow. Unfortunately, most Pakistani political elites are educated in Britain so try to emulate it.
Britain has had 5 PM and 7 finance ministers since Brexit. Paris is now the biggest financial center in Europe. I wasn't sure if the presenter in this clip was talking about UK or Pakistan.
East Asian and American presidential systems are better for economic performance, IMO.
