Sources say Delek not stakebuilding in Great Portland

LONDON (Reuters) - Delek Global Real Estate (DGRE.L), the property arm of Israeli conglomerate Delek Group (DELKG.TA), is not plotting a sharebuying spree in property company Great Portland Estates (GPOR.L), sources said on Monday.

A report in Israeli newspaper Globes suggested that Delek was in talks to acquire a 25 percent stake in the central London property investor, sparking a 1.9 percent rise in Great Portland shares to 481 pence by 3:10 p.m.

But two sources familiar with the matter told Reuters that the companies had had no contact to discuss such an approach, which would also require a public announcement as per stock market protocol.

One source said there was "no substance to the rumours".
