Jeremy Corbyn was given a lesson in harmony - and basic maths - by a 10-year-old violinist during a visit to a youth orchestra.

The Labour leader picked up a violin to play along with the pupils at Faith Primary School in Liverpool.

But he was rebuked by schoolgirl Jessica Kelly as she attempted to teach him his part for playing a note five times instead of four.

"Play that four times," she said, but then when Mr Corbyn failed to follow her instructions she said: "That was five."

Mr Corbyn said: "So maths comes out of music."

The Labour leader joined pupils involved in the In Harmony project run in conjunction with the Royal Liverpool Philharmonic.

Both the party leader and Liverpool metro mayor candidate Steve Rotheram - who attempted to play the cello - joined the youngsters for a performance of a song called D String Rock.

After the lesson, first violinist Jessica said: "It felt great because he is such an important man."

She said Mr Corbyn responded after she told him off: "He listened and then he played four (notes)."

The Labour leader, who has struggled to keep his party in tune with his leadership, said Jessica was a "brilliant" teacher - and suggested he would rather play the fiddle than return to the Labour Party conference in Liverpool.

He said: "I have this ambition that every child in every school should have a chance to learn a musical instrument because I think it does so much good, brings you all together but also gives you a sense of understanding method and probably makes you better at maths and other things as well.

"I think it's really great, I'm really pleased to be here. I love it. I think I might stay all day. It's either this or the Labour Party conference. I think we'll stay. Can I stay all day?"
