After his speech, which occurred just before a performance of hip-hop super group Run the Jewels, the Labour leader sat down with NMEand took the opportunity to condemn the Prime Minister for "the naughtiest thing she's ever done".
Corbyn told the music magazine he was "far too responsible a citizen" to run through a field of wheat, referring to the Theresa May's confession to ITV's Julie Etchingham earlier this month.
He said, tongue firmly in cheek:
I grew up in the countryside in Wiltshire and then later in Shropshire.
I was taught from a very, very early age you walk round the edge of a cropped field.
You don’t walk through a field of wheat because it will damage the wheat.
Not holding back, he added:
I’m totally shocked that anyone would run through a wheat field and damage wheat.
