US insurance broker Aon plans to move its corporate headquarters from Chicago to London.
The company said the move provides greater access to emerging markets and takes better advantage of the strategic proximity to Lloyd's.
Subject to shareholder approval, the move is expected to happen in the second quarter. The BBC reports Chicago will remain the main office for the Americas.
Aon is the main shirt sponsor for Manchester United football club.
At the same time, Aon will change its legal jurisdiction of incorporation from Delaware, USA, to England.
