Alcohol Concern in Wales is warning about the dangers of an online drinking craze that could be linked to the deaths of two young men in Northern Ireland.
The craze - called 'NekNominate' - involves young people filming themselves drinking a pint or more of alcohol and then nominating friends on social networking sites to do the same thing.
In March this year, South Wales Police carried out test purchases in Cardiff with 15 year olds to find out whether they could buy alcohol from major supermarket websites.
It found that alcohol could be purchased by agreeing the website terms and conditions and having a debit card and email address.
It also found that in 44 per cent of the test cases, alcohol was given to underage test purchasers without any requests for proof of age.
Children and young people in Wales are using online supermarket sites to buy alcohol, according to a new report from Alcohol Concern Cymru.
The 'On Your Doorstep' report found 15 per cent of the 14-17 year old surveyed had successfully bought alcohol online and the majority found it easy to do so.
Alcohol Concern Cymru is calling on supermarkets to review their existing age checking procedures to make sure they are fit for purpose and ensure delivery staff are given appropriate training.
The charity also wants there to be more test purchasing by police and trading standards to assess the severity of the problem.
A common New Year's resolution is to cut down on drinking - but one alcohol charity is asking us to pledge to stay dry for a whole month.
Alcohol Concern Cymru says the challenge will enable people to see how dependent they really are on the drink.
