Main results concerning allowable additional symmetries of axially symmetricelectrovacuum spacetimes are summarized. These are translational Killingvectors and the boost Killing vector. However, this is only the boost symmetrythat does not exclude radiation and permit a spacetime to be asymptoticallyflat with global null infinity.Comment: 2 pages, contribution to the 9th Marcel Grossmann meeting (MG9),  Rome, July 200
