Help with identification please

This prickly plant has popped up in my garden and I have no idea what it is. It has tiny thorns all down the stem but the leaves are attractive. Any help on identification would be much appreciated.
A keeper or another contender for the compost bin?

 

Am not certain, but I want to say hogweed. Please cross reference this and check. If so, dont touch it, can leave very nasty blisters. Am happy to be told Im wrong by others, its just that Ive seen hogweed growing by my local canal and it looks like very similar to when its small, gets bigger than shown in the picture.

 

Thank you for your reply Petals. I'm not sure about it being hogweed because it's quite small and has thorns but I'll dig it out just in case.

 

alana @PetalsonthePavingSlabs may be correct by this pic of hogweed

@alana not sure it's a hogweed due to prickles on the stem. Could be Rubus lacinatus (cut leafed blackberry) have a look at Rubus laciniatus | NatureSpot You will probably still want to remove it.

 

Definitely one of the brambles. We get lots of these popping up where the birds sit after eating the fruit from our thornless cut leaf variety.

 

Nigel you could be right mate
