The approval in separate shareholder meetings in Toronto and London clears the way for completion of the deal on April 17, the two firms said.

A statement issued from Thomson's operations headquarters in Stamford, Connecticut, said shareholders approved the plan overwhelmingly.

It came moments after shareholders of Reuters voted in favour of the deal at a special meeting in London.

The takeover will create the biggest provider of financial information to trading rooms, overtaking current market leader and US rival Bloomberg, and will merge the media operations of Thomson and Reuters.

Thomson agreed last year to buy Reuters for 8.7 billion pounds (S$23.6 billion), creating a combined business called Thomson Reuters that will be led by Reuters' current chief executive Tom Glocer.

'Thomson and Reuters will each now seek court approvals in Canada and the United Kingdom, respectively,' the Thomson statement said. 'The acquisition is expected to close on April 17, 2008.'

Regulators on both sides of the Atlantic have already cleared the acquisition, after requiring the divesting of some assets.

Along with the privately held US group Bloomberg, Thomson and Reuters currently dominate the market for providing financial data to banks, investment funds and other financial services firms. Many financial operators work with 'Bloomberg screens' or 'Thomson screens,' or both.

To satisfy regulators, Reuters is to sell a copy of its databases of earnings estimates, company and economic data as well as broker research reports. Meanwhile, Thomson would sell a copy of its company financial database business.

At the time the deal was announced, the two companies estimated that a combined Thomson-Reuters would have 34 per cent of the financial information and data market compared with Bloomberg's 33 per cent.

Reuters currently controls 23 per cent and Thomson 11 per cent.

The takeover was announced last year amid a flurry of deal-making in the financial information market which also saw media-entertainment conglomerate News Corp scoop up Wall Street Journal owner Dow Jones.

Although 90 per cent of Reuters' revenue comes from financial services, the company is better known to the general public as a news agency with some 2,400 journalists in 131 countries.

Thomson meanwhile operates Thomson Financial News with 335 journalists around the world. -- AFP
