GDF could sweeten Power offer

French energy giant GDF Suez is believed to be considering tabling a revamped offer for British rival International Power (IP), the FTSE-listed company valued at £5bn. Talks between the pair broke down last month after GDF offered to transfer assets into International Power in return for a majority stake. But IP’s chief executive Philip Cox said the bid undervalued the business, which has stakes in more than 45 power stations around the world.
