JPMorgan Chase & Co. (NYSE:JPM) is currently in negotiations to lease a substantial amount of space in the Canary Wharf office building that previously served as the UK headquarters for Credit Suisse.

One Cabot Square was one of the first buildings completed at Canary Wharf, which was strongly supported by Credit Suisse First Boston chair at the time, Michael von Clemm. The lender was among the dockland financial district’s original tenants. The 540,000 sq ft building is leased until 2034.
