A trio of Singaporean firms have lined up to advise as breweries Heineken and Kindest Place vie to buy a stake in Tiger beer owner Asia Pacific Breweries (APB).

Duane Morris & Selvam, the local arm of US firm Duane Morris, is leading the advice for Heineken on its $5.1bn (£3.3bn) bid to buy the outstanding 58% stake in APB that it does not already own. The firm fielded a team led by local managing partner Arfat Selvam.

Singapore firm Stamford Law is acting for the seller, Asian food and beverage company Fraser & Neave, led by M&A director Lean Min-tze.

Meanwhile, WongPartnership is acting for Thai brewery Kindest Place, which in a surprise move last week challenged Heineken's bid to take the full remaining stake with a higher offer for Fraser's direct 7.3% share in APB. Head of corporate NG Wai King acted as the primary adviser.

Heineken must now decide whether to raise its offer or risk losing the stake. Kindest Place's bid will lapse on 16 August.

APB was originally established in 1931 through a joint venture between Fraser and Heineken under the name Malayan Breweries with the company later renamed APB in 1990.

The news comes after a number of acquisitions for Heineken in recent years, including its £412m purchase of the RBS Galaxy pub estate in December 2011, which has seen it triple its number of UK outlets, adding 918 new premises to its already existing 462-strong fleet and making it one of the largest pub operators in the UK.

Freshfields Bruckhaus Deringer acted for Heineken on the deal with CMS Cameron McKenna advising RBS.
