  This note explains a construction of a Poisson manifold whose symplectic
foliation describes a deformation of a moduli space of meromorphic connections
with unramified irregular singularities. In particular, this deformation of the
moduli space corresponds to the unfolding of irregular singularities of the
meromorphic connections. This is an announcement of some results in the
forthcoming paper.
