Abstract: We show that every non-amenable finitely generated group admits
a system of generators such that the Bernoulli edge percolation on the
corresponding Cayley graph has a non-empty non-uniqueness phase. We also
discuss an application to measure preserving ergodic actions by
non-amenable countable groups on standard Borel spaces.
