Retail sales values in the UK, on a like-for-like basis, grew 1.4% in June 2012 from the same month a year ago, when they fell 0.6%, according to the data released by British Retail Consortium (BRC ).

During the same month, retail sales were up 3.5%, on a total basis, against a 1.5% increase registered in June 2011.

Food and drink, clothing and footwear and online all performed particularly well during the week preceding the Jubilee .

The organisation said the remainder of the month proved much more challenging throughout the sector.

Discretionary and big-ticket items continued to struggle as cautious consumers tightened their purses on these items.

Online sales of non-food items showed stronger growth again in June, rising 12.1% against growth of 11.5% last year.

BRC director general Stephen Robertson said June was saved by the feel-good lift of the Jubilee, showing how crucial these temporary factors are in the difficult trading conditions.

"A trip to the shops played a big part in preparations for the occasion. The week leading up to the long weekend was a stand-out for the retail sector," Robertson added.

"Sadly the soggy celebrations over the Jubilee weekend itself, which heralded the start of the wettest June on record, were followed by far weaker business for the rest of the month.

"Belts were tightened again and the lower temperatures cooled demand for summer fashions and outdoor leisure goods.

"With the first half of the year complete, we can see total sales growth between this January and June was no better than in 2011. It’s clear a permanent upturn in confidence and spending has yet to happen."

KPMG retail head Helen Dickinson said the double whammy of uncertain sales levels and ongoing promotional activity continues to hit profits and cash flows.

"Retailers are fervently hoping that the summer of sport will raise cash for their coffers. But the reality is that any benefit from the Olympics will probably be concentrated in the South East and provide more of a boost for food than non-food," Dickinson added.
