TORONTO (Reuters) - Thomson Reuters Corp TRI.TOTRI.N Chairman David Thomson urged the company's board of directors to seek better terms for its $17 billion sale of a large chunk of its business to Blackstone Group LP BX.N, the Wall Street Journal reported on Thursday, citing people close to the deal.

Blackstone last month agreed to buy a majority stake in Thomson Reuters’ Financial & Risk division, which competes against privately held Bloomberg in providing bankers and investors with news, data and analytics.

Executives with Woodbridge Co, a private Toronto firm that holds the Thomson family’s majority stake in Thomson Reuters, disagreed with David Thomson and supported the deal, the newspaper said. The Thomson family owns 64 percent of Thomson Reuters through Woodbridge.

Woodbridge CEO David Binet, who is also deputy chairman of Thomson Reuters, could not be reached for comment. A spokesman for Thomson Reuters declined comment.

Thomson eventually voted in favor of the deal, but only after telling other directors he was concerned they had not sought a higher price or considered other potential buyers for the business, according to the newspaper, which did not identify its sources.

Blackstone last summer initiated talks to buy a majority of the Financial & Risk business, a deal strongly supported by Thomson Reuters Chief Executive Jim Smith and directors including Woodbridge’s Binet, according to the newspaper.

Reuters News will remain a unit of Thomson Reuters and provide news to the Financial & Risk business after the deal is completed.
