August was baptised in a rare double royal christening in Windsor with his second cousin, Lucas, the son of Mike and Zara Tindall, in the presence of the Queen, who has been under doctors’ order to rest for more than a month.
In June last year, Eugenie thanked NHS staff for saving Mr Brooksbank’s life after he fell ill with Covid-19.
At the time, Eugenie, her husband, mother-in-law Nicola and brother-in-law Tom were warned to prepare for the worst when Mr Brooksbank was put on a ventilator for five weeks.
“George came back home to us the other day, so happy and as the miracle man, as he called himself,” she wrote.
He was in hospital for nine weeks.
After a tracheotomy, his condition gradually improved and he was moved to a ward at the Royal Brompton Hospital which specialised in heart and lung conditions in people recovering from Covid-19.
He also underwent a further period of rehabilitation at an institution in Roehampton.
Mr Brooksbank also thanked staff himself for the “incredible” treatment he had received.
A source told MailOnline that Mr Brooksbank was not the same after contracting Covid and had been unwell for some time, but that it was “wonderful” he was able to meet his grandson.
Old Etonian Mr Brooksbank, who attended Eugenie and Jack’s wedding in 2018, was a retired chartered accountant and company director.
