More than 10,000 extra police officers across the country are to be armed with Tasers.
The Home Office said it was making £10m available to increase the number of trained and equipped officers following violent attacks where officers have been hit by cars and stabbed.
Police Federation, which represents rank-and-file officers, said they should be available to those who want them, and can save lives.
Priti Patel the home secretary, said: “I’ve been completely appalled by the recent spate of serious assaults on police officers, which is why I’m giving chief constables the resources to dramatically increase the number of their officers who carry Tasers.
“They keep us safe and now I’m giving them what they need to keep themselves safe on the job.”
Officials said the funding would allow at least 10,000 more to be armed after attending a required three-day training course.
