Gianluca Buonanno is promising locals in the town of Borgosesia, in the northern Piedmont region, 250 euros ($284; £184) towards the cost of a firearm, La Repubblica website reports . Mr Buonanno, a member of the the right-wing Northern League party and also an MEP, says the cash - dubbed the "gun bonus" - represents about 30% of the cost of a gun. His announcement comes in the wake of a debate over self defence laws in Italy, after allegations that a pensioner shot dead an intruder in his home near Milan on Monday night. Police have now launched a voluntary manslaughter investigation, according to La Stampa
