I thought this was some kind of Vetch - but my neighbour doesn't think so. I've looked online and I think the leaves aren't right. So it's really bugging me.
We go for dog walks at the fields behind us ( my neighbour has always taken ours when he does his dog walk as he no longer has a dog)  so a win win for ours as they get double walks
Anyway there's a crop field that has been thickly edged with this? 
What do you think?

Hairy vetch? https://www.cotswoldseeds.com/species/205/hairy-vetch

The plant is a bit wilted - but look at the leaves. All the leaves start from a central point. They don't grow along the stem?
The flowers and pods are a perfect match.

Leaves look a little lupin like maybe?

I think Jimny's right,  it's a blue lupin grown for forage.  I found it on a website but have no idea how to insert a web page in a post .

JJB - Copy the webpage and paste in the post.

Definitely lupin leaves! Thank you it is Blue lupin. I was sure it was vetch until the neighbour said - strange leaves for vetch and left the plant on my wall yesterday for me to check. He will be chuffed that I had it wrong

I would've guessed vetch too Scarlet
