N2 - A subalgebra B of a Leibniz algebra L is called a weak c-ideal ofL if there is a subideal C of L such that L = B + C and B ∩ C ⊆ BLwhere BL is the largest ideal of L contained in B. This is analogousto the concept of a weakly c-normal subgroup, which has been studiedby a number of authors. We obtain some properties of weak c-idealsand use them to give some characterisations of solvable and supersolvable Leibniz algebras generalising previous results for Lie algebras. Wenote that one-dimensional weak c-ideals are c-ideals, and show that aresult of Turner classifying Leibniz algebras inwhich every one-dimensional subalgebra is a c-ideal is false for generalLeibniz algebras, but holds for symmetric ones.
