Banks and financial firms that buy information from Thomson and Reuters are questioning Thomson’s £8.5 billion takeover of Reuters on the ground that it would restrict choice and significantly reduce competition.

Angela Knight, the chief executive of the British Bankers’ Association, said: “As with any service where one starts to reduce the numbers of players, there will be questions about what that means in terms of choice and in terms of cost-effectiveness for the users concerned.”

Her intervention over the proposed deal – which could be formally agreed as early as this week – followed an attack from another customer body, the Information Providers Users Group. Colin Wright, its staff consultant, said that its members – which include Investec and JPMorgan – said that competition kept providers “lean and mean”. He said that the group had not ruled out an approach to the competition authorities.

The growing concerns of customers about a tie-up of the No 2 and No 3 financial information providers are expected to increase the chances of tough scrutiny of the deal by regulators in Brussels and in the United States.

Analysts have highlighted “considerable deal risk” from regulatory scrutiny. Some believe that completion of any get-together could be delayed into next year or that the deal could be blocked altogether.

Reuters and Thomson confirmed in a joint statement this month that they were in talks about a cash-and-shares tie-up. They said that the enlarged group would lead to annual savings of £250 million after three years. It would have a similar market share to Bloomberg at about 34 per cent.

Some customers had hoped that Thomson could have created a bigger third force in the market by buying up smaller specialist firms instead.

Reuters and Thomson are understood to feel confident that the Reuters Founders Share Company – the 18-member body that has the right to block a takeover if it believes that the integrity of the company’s news reporting is under threat – will approve the deal.
