Asda, the UK subsidiary of US retail giant Wal-Mart, today [Wednesday] announced it would lobby the government to liberalise the UK pharmacy retail sector to introduce more competition. The group said potential savings for consumers could reach £420m (US$597.1m) per year. The Office of Fair Trading is currently looking into a potential liberalisation of the regulations governing new pharmacy licences following criticism that the current regulation limits competition to the detriment of the consumer. Last year resale price maintenance for over-the-counter (OTC) drugs was abolished, heralding potential loosening of the market.
