The Royal Wedding and the FA Cup have bumped up sales of burgers, sun cream and non-alcoholic beer, with shoppers splashing out £415m on the Friday before the event.
The grocery market rose by 2.7% in the three months to 20 May, up from 2% reported a month ago, according to Kantar Worldpanel.
“The sun shone on the grocery market over the past month with record-breaking temperatures, a bank holiday weekend and royal wedding fever all contributing to a bumper period,” said Chris Hayward, a consumer specialist at Kantar.
