LONDON — In honor of Andy Murray, who won the Wimbledon Sunday, supermarket chain Morrisons changed the name of their stores to “Murriwins.” “Congrats to #Wimbledon Champion @andy_murray! How are you celebrating? We've given our store a special makeover,” the store tweeted. Murray became the first British men's singles champion at the tournament since Fred Perry in 1936, after beating the world number one in straight sets 6-4, 7-5, 6-4. Reactions on Twitter included one from Prime Minister David Cameron, saying: “It was a privilege to watch @Andy_Murray making history at #Wimbledon, and making Britain proud.” — SG
