SABMiller has secured a temporary court injunction to block Diageo subsidiary East African Breweries Ltd from buying a stake in a rival brewer in Tanzania.

A High Court judge in London today (18 August) granted the injunction, which blocks East African Breweries Ltd (EABL) from breaking its partnership with SABMiller-controlled Tanzania Breweries and investing in a rival brewer in the country.

The injunction will remain in place pending arbitration proceedings at the International Chamber of Commerce (ICC).

Neither firm was able to confirm a timetable for the ICC hearing, although the injunction will expire on 17 January 2011.

Kenya-based EABL owns a 20% stake in Tanzania Breweries, which is Tanzania's largest brewer and is 52.83% owned by SABMiller.

However, SABMiller accused EABL of breaching its contract after Diageo announced that the brewer had signed a deal to acquire a "substantial interest" in Serengeti Breweries, Tanzania's second largest brewer, for an undisclosed fee.

A spokesperson for Diageo told just-drinks today that the group "have made clear that our future [in Tanzania] is with Serengeti".
