After he had announced his intention to retire on health grounds, the local Unionist Association selected as its candidate F. East. Muntz, who had contested Rugby in 1900.
However, Muntz was himself forced to withdraw due to ill-health, and consideration was given to asking Green to stand again, since his health had improved. The Times reported that the Liberal Party candidate Clarendon Hyde had been nursing the constituency for some time, and that local unionists wanted Green to reconsider his retirement.
However, Green did not stand again and the Unionist candidate Alfred Bird lost the seat to Clarendon Hyde. He died on 17 November 1941 in Langton, Courtenwell, Tunbridge Wells, aged 72.
