We prove that the problem of the existence of a discontinuous separately continuous function f : X × Y → R for any non-discrete Tychonov spaces X,Y of countable pseudocharacter is equivalent to NCPF (Near Coherence of P -filters) which is independent of ZFC. Also for every non-discrete Tychonov space X we find an abelian topological group G of countable cellularity and a discontinuous separately continuous function f : X × G → R.
