Abstract: In this paper, the class of weakly left C-wrpp
semigroups which includes the class of weakly left C-rpp semigroups
as a subclass is introduced. To particularly show that the spined
product of a left C-wrpp semigroup and a right normal band which is a
weakly left C-wrpp semifroup by virtue of left C-full Ehremann cyber
groups recently obtained by authors Li-Shum, results obtained by
Tang and Du-Shum are extended and strengthened.
