The investment arm of the Qatari government is understood to have nudged ahead of rival Pramerica, the US financial institution, to secure the stake in the Cit of London skyscraper scheme.

Halabi fell out with the other two partners in the scheme, CLS and Sellar Properties, in a long-running dispute over the respective sizes of stake and project management fees.
