A process is described for the preparation of a solid component of catalyst active in the (co)polymerization of ethylene and able to give (co)polymers of ethylene having from middle to wide distribution of the molecular weight and monomodal distribution of molecular weights, in processes operating in a single step, in suspension or in gaseous phase. Said solid component of catalyst contains magnesium, chlorine, silicon, titanium and at least another transition metal on a solid, granular and porous carrier and is obtained by treating the carrier, in succession, with: a compound of a metal selected from hafnium, zirconium or vanadium; a magnesium dialkyl or magnesium alkyl halide; a silicon chloride; and a titanium compound.
