A “fiercely intelligent” former regional journalist who was still working until recently has died aged 77 after a short illness.
Sean, pictured, worked as a sub-editor on Reuters world desk at 85 Fleet Street before embarking on a successful freelance career spanning five decades.
He was working right up to his death, specialising in business, scientific and medical journalism.
Friend and former colleague John Marquis said: “Sean was a lovely chap, fiercely intelligent, endlessly curious and a terrific journalist in his field.
“Everyone who knew him will miss him a lot.”
Sean, a Cambridge graduate, was the younger son of the well-known High Court judge Sir Helenus Milmo, who was a lawyer at the Nuremberg Trials in the 1940s.
His sons Cahal and Dan followed him into journalism. Cahal is chief reporter of the i newspaper, while Dan is deputy business editor of The Guardian.
He is also survived by wife Marion, who often worked with him as a researcher.
