Deutsche Telekom is interested in raising its stake in its Greek unit OTE, a Greek Finance Ministry official said yesterday after the government decided to sell part of its holding. According to a Reuters report, the Greek government has a put option until the end of the year to sell a 10 percent stake in the former monopoly to Deutsche Telekom, which already owns 30 percent of the company. The government said on Friday it would reduce its 20 percent stake in OTE by the end of the year, as part of a five-year, EUR50 billion privatisation.
