Parental drinking is linked to more than a third of cases of severe child abuse and neglect in England.
A new study has found that alcohol misuse was implicated in 37% of cases where abuse or neglect led to a child’s death or serious injury between 2011 and 2014.
Liam Byrne MP warned that parents who misuse alcohol can cause ‘horrific’ problems for their children.
Some 15% of children have their bedtime routine disrupted by their parents’ drinking, and 18% are embarrassed at seeing their parents drunk.
Children living with alcohol-dependent parents reported feeling socially isolated, but were reluctant to seek help due to feelings of stigma, shame and guilt about not wanting to betray their parents.
Freedom of Information trawls revealed that more than half of councils still lack a strategy to help children of alcoholics, and that referrals to alcohol treatment services are falling in more than 50% of local authorities.
It was also found that 92% of the 53 councils that provided information to the study are cutting their budgets for alcohol and drug treatment services.
Cuts differ in size, ranging from an £87,000 cut in Wolverhampton, to a £9.6million one in Lancashire.
The average drop in local authority funding was around £198,000.
However, around 61% of care applications in England involve the misuse of alcohol and/or drugs.
The All-Party Group for Children of Alcoholics report called for better funding to help children affected by parents who drink.
Mr Byrne, who lost his father to alcoholism in 2015 and is chairman of the parliamentary group, said: ‘Millions of parents drink too much and their misuse of alcohol causes horrific problems for their children.
‘Parental alcohol misuse scars kids for life and can lead many into a life of drinking too much themselves.
‘Our campaign has now won a new commitment from Government for a national strategy to stop parental alcohol misuse.
‘This new report shows just why the Government must act fast to put an effective plan in place.’
A spokeswoman for the Department for Health and Social Care said: ‘We are acutely aware of the impact some parents drinking can have on their children – that’s why work is well underway on a new Children of Alcoholics Strategy, which will look at what further support we can provide to families to tackle alcohol harms.
‘This comes in addition to our new higher duties to target cheap, high strength cider and the UK Chief Medical Officers’ guidelines, which help adults make informed decisions about their drinking.’
