In a recent paper \cite{3}, a semi-stable degeneration of moduli space ofHiggs bundles on a curve has been constructed. In this paper, we show thatthere is a relative log-symplectic form on this degeneration, whose restrictionto the generic fibre is the classical symplectic form discovered by Hitchin. Wecompute the Poisson ranks at every point and describe the symplectic foliationon the closed fibre. We also show that the closed fibre, which is a varietywith normal crossing singularities, acquires a structure of an algebraicallycompletely integrable system.
