I have lost my travel document abroad and now I want to get back to the uk urgently how can I get back to the uk and can I apply for the emergency travel document instead of TD112

You will need to go to the local UK embassy or consulate and they can arrange all this for you.

Thanks for the answer but I was looking for a more detailed answer and the process to go through

That is the detailed answer, call or go to your nearest embassy for your nation. They can arrange quickly either the paper work or another way for you to return home.

OK thanks and one more thing do you think they can help me with the emegency travel document thing
