People familiar with the matter told Reuters that Deutsche Telekom is likely to win unconditional EU antitrust approval for its bid to buy Swedish peer Tele2's Dutch unit.

The report sent shares in Tele2 rallying 9 percent, while Dutch market leader KPN surged more than 4 percent and the broader European telecoms index <.SXKP> shot up over 3 percent in afternoon trading.

"The Dutch telecom market will consolidate from four to three players with the approval of the Deutsche Telekom - Tele2 deal, reducing competition," said Jauke de Jong, a research analyst at AFS Group in Amsterdam.

He said the deal also indicated that the European Commission could have a more favourable stance towards consolidation in other European countries such as France.

Several telecoms shares such as Vodafone, Telefonica, Telecom Italia, Swisscom and BT and Orange spiked higher on the report.

Telecoms have been underperforming over the past few years as pricing pressure, competition and costly network upgrades have been squeezing margins, keeping investors away.
