Hong Kong- and Shenzen-based Cheung Kei Group, or CKG, is purchasing 20 Canada Square, a 12-story office Canary Wharf office building currently occupied by S&P Global (formerly known as McGraw Hill) and oil firm BP. 

Global banks including J.P. Morgan and Goldman Sachs have revealed plans to minimize their staff in London by moving to Frankfurt, Paris or Dublin as a result of the Brexit vote. Many of them are also some of Canary Wharf's largest tenants.

CKG was advised, among others, by Credit Suisse's global real estate division, which is part of the wider asset management and private banking arm.

The Swiss bank said its private bank in Asia and its Swiss-based asset management arm closely cooperated in closing the deal, which marks the Hong Kong investor's first British acquisition.

Credit Suisse itself is just across the square from the property. The Swiss bank is also looking to reduce headcount in London.
