Do I need a passport to leave the UK if my destination doesn't need me to have one?

Following on from this question: Will I be eligible for an Emergency Travel Document?, I'm wondering:

If the US doesn't require a passport if I'm entering on a Green Card, does the UK require me to have one to leave?

If not, would me Green Card be sufficient identification to check in and board my plane?

Who makes this call? UK Border Agency? My airline? Someone else?

Best Answer

There's no law that you require a passport (in date or otherwise) to leave the UK.

It's simply up to the airline whether they wish to transport you to the destination. They will not transport you if they think you will be denied entry, because the airline gets fined for this.
