The European Commission will approve the plan for Hewlett Packard (HP) to buy Compaq, according to a Reuters' source.
The source, which came from within the European Union, told the news agency that the Commission would not impose conditions on the proposed $25bn (£17.5bn) takeover deal.
Last year, the Commission blocked General Electric's planned purchase of computer group Honeywell, which attracted criticism from the US. The Federal Trade Commission is still to rule on the HP/Compaq merger.
The deal, described by HP this month as a necessary step, will be decided by shareholder vote in early March.
