Police and courts will get extra powers to deal with people who beat up their partners under revamped laws championed by Swindon MP Julia Drown.
Victims of domestic violence are also set to get tougher protection under the legal system, with new safeguards to shield them from repeated abuse in their homes.
Ms Drown, the MP for South Swindon, said the moves were the biggest shake-up of domestic violence laws in 30 years.
She said: "I feel proud that the work we have done in Swindon and at a national level is having an effect. These reforms are long overdue. Domestic crime can be devastating for victims and they need to know they will get the full support of the law."
The Domestic Violence Bill, which is currently before parliament, includes beefed-up punishments for offenders breaking restraining orders.
It will become a criminal offence to breach a molestation ban, with a maximum penalty of up to five years in prison.
Common assault the charge faced by many who beat their partners will also be an arrestable offence.
And courts will be able to slap-on restraining orders even if a defendant has been acquitted of a crime - as long as the authorities fear there will be future harassment.
Ms Drown played an important role in pushing for these measures to be included in the Bill when it was being drawn up last year.
There will also be a Victims Fund to put more money into support.
, information and advice services.
The Labour backbencher said: "I'm pleased in Swindon we already have excellent support services for victims of domestic violence.
"But what has been clear from my contact with those who have suffered abuse is there hasn't always been the necessary powers when it comes to enforcing restraining orders and giving full protection.
"These new laws should fill that gap."
The Bill is due to pass through parliament and into law this summer.
