Bloomberg, the media empire founded by the current Mayor of New York, has shortlisted three sites for its new London headquarters.

The New York head office is considering taking 300,000 to 400,000 square feet in either Watermark Place, the UBS and Oxford Properties development next to the Thames, which is due to open next year; Minerva's The Walbrook, under construction in the City; and Ropemaker Place, which is being developed by FTSE 100 giant British Land.
