The government's decision to block the £2.3bn sale of Bass's brewing arm to Interbrew will be reviewed in the High Court on May 9.

The hearing will challenge the Competition Commission's finding and its remedy to sell the brewing assets in one piece to one buyer by the end of June.

The likeliest suitor for the assets is thought to be South African Breweries but Interbrew could break up, sell, or merge the division in several ways.

Analysts, however, believe a one-off-sale to one buyer could fetch the best price.

The court is expected to make a decision by July which would postpone a sale until the end of the year.

Meanwhile, Belgium is still considering whether to take legal action to challenge the UK decision. The Belgian government said last month it would file a complaint with the European Court of Justice but it has made no formal complaint so far.
