Aberdeen Asset Management has welcomed a court ruling that SABMiller shareholders can be treated as two separate groups when they vote on a takeover by Anheuser Busch InBev - and still plans to reject the deal. 

The £79bn deal headed to the courts as SABMiller sought to make sure the deal treated investors fairly, given its two largest shareholders were offered different terms to help them cut their tax bill. 

Aberdeen said: "We are pleased the court has acknowledged the reality of the situation which will help to ensure that the views of the rest of the investor base have due weight. As we have already indicated, we intend to vote against the deal as we are uncomfortable with the structure and believe it undervalues the company."

It has called on others investors to help ensure SABMiller remain a standalone company.
