Can you go to Poland on a coach without passport?

hi i have a polish friend that has lost her passport and she is convinced she can get back to poland without a passport on a coach is this true ??

It is possible (and normal for many folk) to travel with an ID card.

But it does depend which countries one is travelling through.

info needed
I should think this would be OK I have seen many people do this on the coach which does the normal route London - Dover - Calais -----Poland

yes - if she has her Polish ID card

Just dont get it,why cant I just flash my driving licence to some bus driver and escape my own country but non Brits can come and go as they please? Right narks me off that. Fair play to you guys that can,but,argh.....once more Britain seems to have signed up to the EU dream of open borders and free movment of every bl**dy people but its own !!! GGrrrrr....;)

edit to clarify,my passport ran out last year and it pee's me off I have to spend a small fortune when I have no short term plans to leave Europe.......

brits seem to be against ID cards.

Thats the thing. I am dead set against ID cards.
Silly fact, Did you know that even in WW2 you did not legally have to have a photo attached to your national ID card?
We got rid of them pretty much straight away as a wartime measure. They just go completely against the grain of Magna Carta and all that,free and unfettered travel anywhere within our own lands.

Not to get to deep,but europe ,mainland europe tended to keep stuff like Serfdom and bonded labour untill not that long ago. Im not saying its natural for you guys to be serfs,but,its in your fabric that "someone" has always known you and kept track of you in someway.

So,Im fine with showing ID at a countries borders,its that countries perogative to see who is coming and going,what Im not fine with is tthat allegedlly we dont have to anymore,when in fact,we do,and we citizens have to show more "official" documents than others do. (yes,I know your ID is official ;) )
