Influence of pressure on the phase transition temperature T_C and on the spontaneous magnetisation M_{0} of highly Sr substituted and oxygen nonstoichiometric La_{1-x}Sr_xCoO_{3-δ} samples was investigated. An increase in T_C and M_0 with pressure in investigated samples was found, indicating strengthening of ferromagnetic double exchange interactions, and the expansion of volume of ferromagnetic phase as a~result of enhancement in ferromagnetic interactions in both cluster-glass and long range ferromagnetic states. We did not observe clear correlation between changes in pressure coefficient dT_C/dP and changes in the formal oxidation state of the Co ion.
