After the war, he became the
tai-pan of the British Hong Kong
hong Hutchison, better known as Hutchison Whampoa. He overstretched his finances, which resulted in
HSBC taking over the firm, replacing Clague, and led to the sale of Hutchison Whampoa to
Li Ka-Shing's Cheung Kong in 1979. Clague was also one of the commandants of the
Royal Hong Kong Auxiliary Police Force, and a member of both the
Executive and the
Legislative Councils of Hong Kong, when he succeeded
Cedric Blaker on 21 March 1958. From 1950 to 1951 he was President of the Gunners Roll of Hong Kong. Clague owned a
lodge at
Kam Tsin in the northern
New Territories alongside many other wealthy people. He was also a
racehorse owner and one time chairman of the
Royal Hong Kong Jockey Club; it was under his tenure that the
Sha Tin Racecourse was developed. The
Clague Garden Estate in
Tsuen Wan is named for him, as he was also one of the longest serving chairmen of the
Hong Kong Housing Society. ==Personal==
