LONDON (Reuters) - British supermarkets were boosted by the royal wedding and warm weather in the 12 weeks to May 20, industry data showed on Wednesday, with third and fourth placed Asda and Morrisons outperforming their bigger rivals.

Kantar Worldpanel said the country's second biggest grocer Sainsbury's SBRY.L posted the lowest sales growth and continued to lose market share.

Sainsbury’s, which last month announced plans to acquire no.3 Asda, posted sales growth of 1 percent in the period, behind market growth of 2.7 percent, and its market share dropped 0.2 percentage points to 15.7 percent, according to the Kantar Worldpanel data.

The country's biggest grocer Tesco TSCO.L posted sales growth of 2.2 percent, with sales at Walmart-owned WMT.N Asda up 2.8 percent, and no.4 player Morrisons MRW.L posting a 2.9 percent rise.

“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,” Kantar’s consumer specialist Chris Hayward said on Wednesday.

Sales of BBQ-related foods like sausages and burgers soared, as did demand for sun cream, Kantar said.
