The creature was discovered on Seilebost Beach in the Outer Hebrides and a whole range of plastic, netting, rope, cups and bags were found inside the mammal.

The Scottish Marine Animal Stranding Service (SMASS) is investigating why the whale ended up with so much pollution inside it, and they claim the whale ''wasn't in particularly poor condition''.

In a post on Facebook page, the group said: ''Whilst it is certainly plausible that this amount of debris was a factor in its live stranding, we actually couldn't find evidence that this had impacted or obstructed the intestines.

''This amount of plastic in the stomach is nonetheless horrific, must have compromised digestion, and serves to demonstrate, yet again, the hazards that marine litter and lost or discarded fishing gear can cause to marine life.

''It is also perhaps a good example that this is a global issue caused by a whole host of human activities.''
