Hammerson is back on full takeover alert this morning after private equity group KKR was named as a possible suitor for the UK’s fourth-largest REIT.

Shares soared 5.5% to 1655p in early trading following reports that KKR, who last month mooted a £9.7bn bid for Sainsbury’s, was evaluating a possible approach.

KKR is the latest in a growing series of companies running the rule over John Richards’ retail property specialist.

Last week, Property Week revealed that US REIT Vornado was plotting to break into the UK property market and was interested in making a bid for Hammerson.

Other admirers are thought to include Europe’s largest property company Unibail and GE Real Estate.
