It is shown that an arbitrary singular Lagrangian theory (with first and second class constraints up to N-th stage in the Hamiltonian formulation) can be reformulated as a theory with at most third-stage constraints. The corresponding Lagrangian L can be obtained by pure algebraic methods, its manifest form in terms of quantities of the initial formulation is found. Local symmetries of L are obtained in closed form. All the first class constraints of the initial Lagrangian turn out to be gauge symmetry generators for L.
