Due to Guy's controversial connection with the Transatlantic Slave trade, the statue has come under scrutiny.

Due to a brief period where the company attempted to sell slaves in Spanish America, he is seen as a controversial figure.

The Mayor of London Sadiq Khan established the Commission for Diversity in the Public Realm in order to review statues and monuments in the city.

The Guy's and St Thomas' NHS Foundation Trust announced that they would work with Khan on the issue.
