British wholesaler Booker said today it expected its £3.7 billion takeover by Tesco to complete early next year, as it reported a 9% rise in first-half profit. 

The agreed deal is currently being investigated by UK regulator the Competition and Markets Authority (CMA).

Provisional findings are expected by the end of the month, ahead of a final report by the end of the year. 

"It is expected that the merger will complete in early 2018, subject to, amongst other things, the necessary shareholder approvals," Booker said. 

The group supplies the Budgens, Londis, Happy Shopper and Premier convenience chains, catering firms such as Wagamama and Carluccio's, and also operates cash and carry business Makro. 

Booker said it made a pretax profit of £88m in the 24 weeks to September 8, up from £81m the same time last year. 

Total sales rose 2.5% to £2.6 billion with progress in both the catering and retail sides of the business. 

It said non-tobacco revenue in the first four weeks of its new financial year is ahead of last year. 

Booker said it will not be making forward looking statements for the duration of the Tesco offer period.

For each Booker share, Tesco is offering 0.861 new Tesco shares and 42.6 pence in cash.
