Overseeing the Painter

Painting for the tourists under the watchful eye of George Canning.
Canning held several political posts, including that of Foreign Secretary, Treasurer of the Navy and a mere four months after becoming Prime Minister died. (1827).
He played an important role in the war against France. He promised to send more troops to Lord Wellington, however the secretary of war Lord Castlereagh overturned his decision to send the troops to Portugal, sending them to Holland instead.
A bitter argument ensued resulting in Canning being shot in the thigh by Castlereagh.
