LONDON (Reuters) - How retailers respond to the fall in sterling since Britain's June vote to leave the European Union is a commercial decision, British Prime Minister Theresa May's spokeswoman said on Thursday. Britain's biggest retailer Tesco has pulled Unilever goods such as Marmite from its website in a pricing row sparked by the Brexit-induced plunge in the pound. Asked whether the government was concerned about companies using the fall in sterling as a reason to put up prices, May's spokeswoman said: "It is a decision for companies how they market and sell their products ... It is a commercial decision." (Reporting by Kylie MacLellan and Kate Holton, editing by Elizabeth Piper)
