It is illegal to give alcohol to a child under five years of age.
If you are 16 or 17 you can buy or be bought beer or cider
to drink with a meal in a restaurant, but not in a bar.
Except for 16 or 17 year olds having a meal in a pub (see above),
it's against the law for anyone under 18 to buy alcohol in a pub,
off-licence, supermarket or other outlet. It is also illegal to
sell alcohol to under 18's, or for anyone to buy alcohol in a pub
for someone under 18.
The police can confiscate alcohol from anyone they know to
be, or reasonably believe to be, under 18 drinking in a public place
or a place where they have gained access unlawfully.
