Scottish & Newcastle, the brewer at the centre of a takeover battle with Carlsberg and Heineken, is expected to update the City on trading tomorrow.

The brewer, which has rebuffed two bids for the company from Carlsberg and Heineken, will put the strong performance of its Russian joint venture BBH at the centre of the update, according to reports in the Daily Telegraph.

However, Carlsberg has reportedly written to senior S&N employees warning them not to disclose details of the financial performance of BBH, reports the Sunday Times.

S&N CEO John Dunsmore could also announce the sale of S&N's French distribution business Elidis for an estimated £100m, according to the Daily Mail.
