The House of Lords are debating the Referendum Bill and you can watch it here but the debate will appear in Hansard tomorrow, when I shall post a link to it. You can read some of the early speeches here but the full text will not be up till early tomorrow morning. It is worth pointing out that the Lords do not divide on Second Reading so, please, no hysterics about there being no vote after today's debate. There will be Amendments at the Committee and Report stages and then there will most probably be divisions.
In the meantime, here is the Bill as it exists now and as it is being debated in the House of Lords.
