At present the age of consent in the UK is 16.
In Spain the age of consent is 13.
The argument I have heard put forward is that a legal age of consent has little effect on younger people. Spanish girls are said to wait a year longer than English girls before having sexual partners, despite the age of consent being 3 years less.
Also, lowering the age of consent could be beneficial as it would allow youngsters to seek proper contraception and medical care.
Although the argument is persuasive, it does seem to somehow be almost an abandonment of protection of our youngsters in my view.
