A private member's bill to give 16 and 17-year-olds the vote now has little chance of becoming law after running out of debating time in the House of Commons, before it could be put to a vote.

The Representation of the People (Young People's Enfranchisement) Bill, proposed by the Labour MP Jim McMahon, was debated for a little less than an hour and a half.

And the Deputy Speaker Eleanor Laing ruled that was not long enough for her to allow it to be put to a vote.

In theory the debate will resume on a Friday in December, but in practice the bill will be so low on the agenda, it's unlikely to get any debating time.
