"As a precaution, we've increased our stockpiles in Britain in key areas," Schneider told Germany's Frankfurter Allgemeine Zeitung in an interview, to be published on Saturday. "So if it should come to any delays or problems, we'll remain able to serve British consumers."

The head of the Swiss-based group also said that Nestle, which struck a $7 billion (5.53 billion pounds) coffee licensing deal with Starbucks in May and has been exploring options to shed its skin care unit, will continue adjusting its portfolio of brands through acquisitions and divestitures.

"We've got the courage for it and will seize good opportunities to buy," Schneider said. "On the other hand, there will also be businesses we part from because they no longer fit into our strategy, or their growth prospects aren't that good anymore."
