Is it possible to track a package from Poland to the UK?

is it possible to track a parcel sent to the UK from Poland if you have a number? I tried Royal Mail but they say they can not track a parcel sent from abroad. Is there an equivalent to Royal Mail track and trace in Poland?

after you type in the parcel number and click SZUKAJ (Search)
you'll see another window with the following info:

Parcel number: xxxxxxxxxxx
Shipping country: Wielka Brytania
Destination country: Poland
Received:

and below:
Events regarding the parcel:
Data (Date)
Godzina (Hour)
Miejsce zdarzenia (Location of the event)
Zdarzenie (Event)
Informacje dodatkowe (Additional information)

depends what it contains, if its contraban it'll be tracked for you right to your front door - better get the kettle on for 4 customs guys, an armed response vehicle and a van full of pigs !
