MP Dehenna Davison's one-punch justice campaign backed by police leaders A CAMPAIGN seeking “fairer justice” for one-punch assault victims and families has been backed by Durham’s police commissioner. Bishop Auckland MP Dehenna Davison has launched an all-party parliamentary group (APPG) to look at sentencing around single-strike attacks. She launched the campaign, and wrote about it for The Northern Echo, on the 14th anniversary of her dad Dominic’s death following an assault. The Office of the Durham Police, Crime and Victims’ Commissioner has thrown its weight behind the MP’s campaign, saying it is committed to campaigns that raise awareness and educate people about the impact a single punch can have.
