In the first ballot, the 18 age option received 50 votes, the 20 age option received 38 votes and the split-age option received 33 votes.
The final vote between the top two was 69 for aged 18 and 53 for aged 20.
The vote on the age is the only conscience vote in the Alcohol Reform Bill. Debate on other elements of the bill will resume after next week's recess.
It took MPs 2 hours debating the age yesterday afternoon before they decided to keep the status quo and it probably was the sensible thing to do.
We allow 18-year-olds to do everything else, including voting and joining the military, so why should we deny them the right to buy alcohol?
The problem with raising the drinking and purchasing age is it becomes difficult to police and you find police resources are wasted trying to stop people aged between 18 and 21 from drinking.
We already have a major problem with underage drinking, so why create a bigger burden by increasing the number of people who can't drink.
Rather than trying to restrict people doing something they are going to do anyway, why not educate them about responsible and acceptable drinking.
That, of course, starts with us adults setting a good example.
