Bermuda’s new Governor George Fergusson had surgery yesterday but doctors could not save his sight in his left eye, the Foreign and Commonwealth Office (FCO) revealed.
The 56-year-old was assaulted in Hammersmith Cemetery, west London, on Friday night but managed to walk to a nearby hospital.
His attacker stole only a small quantity of cash.
The FCO said Mr Fergusson, who lives in Lambeth with wife Margaret, was still expected to take up the post of Governor on the tiny British overseas territory next month.
He has previously served as Governor of the Pitcairn Islands and high commissioner to New Zealand and Samoa.
A Metropolitan Police spokesman said: “Police are appealing for information and witnesses after a man was attacked in Hammersmith.
“The 56-year-old man was assaulted and robbed at around 7.30pm on Friday, April 20, while walking in Margravine Cemetery and Park, also known as Hammersmith Cemetery.
“A small quantity of cash was taken and, at this early stage, officers are satisfied that robbery was the only motive.”
