United Breweries (UB) Ltd has refused to comment on mounting speculation that US based Miller Brewing and Japan's leading beer producer Kirin Brewery are both reportedly interested in acquiring a minority stake in the company.

In a report by the Indian press, UB said that most of the freshly received proposals were routed through merchant bankers, which made it impossible to confirm the names.

According to the report Vijay Mallya, chairman of UB offered a 26% stake to a foreign partner following "unsolicited expression of interest" from some international brewers, including Singapore based Asia Pacific Breweries and Belgium's Interbrew and Carlsberg.

Mallya has made it clear that he has no intention to trade the majority stake and rejected sell out proposals.

Kirin already has a presence in 40 countries across North America, Europe and Asia as well has markets like China and Taiwan.
