UK retail sales growth picked up last month for both food and non-food chains as warm weather, summer promotions and sporting events helped drive demand.
Total sales in June grew 3.1% compared to the same month a year ago, according to the BRC-KPMG retail sales monitor, following growth of 1% in May.
Food sales grew by 4.1%, up from 3.6% the month before, as grocers continued to increase prices.
Meanwhile, non-food sales increased 2.2%, bouncing back from a 1.1% decline in May.
"Soaring temperatures increased sales of electric fans while sports and leisure equipment was boosted by both the weather and the start of Wimbledon," said Helen Dickinson, chief executive of the British Retail Consortium (BRC).
Home appliances and homeware purchases were notable categories of sales, the report said.
Dickinson said food sales were partly driven by food inflation, which has risen steadily over the course of the year.
Food inflation increased to 3.7% in June, according to figures from the BRC at the start of the month, up from 2.8%, 2.6% and 2.4% in the preceding months.
Warm weather and shopping for summer holidays led to "modest" monthly growth for clothing sales, said Linda Ellett, consumer, retail & leisure expert at KPMG.
"But retailers will be hoping that the buying is not yet complete and that the pace picks up further in July and August as suitcases get packed and the sun hopefully keeps shining."
Research showed that shopper confidence fell back this month, with escalating global tension and economic pressures leaving shoppers "feeling uncertain in the year ahead," according to Sarah Bradbury, CEO of IGD, which provides food and drink sales information to the survey.
"Notably, the number of shoppers expecting food prices to get much more expensive rose from 14% to 20%, reflecting renewed inflation concerns.
"Value sales growth continues to be predominantly driven by inflation with volumes under sustained pressure.
"However, the arrival of new summer ranges and improved weather presents retailers with opportunities to tap into more consumer occasions, particularly amongst higher-income shoppers who remain focused on quality."
