The Green Party is known to release brilliantly funny election videos from time to time, but this could be its best one yet.

Played by five-year-old children, the video features miniature versions of Prime Minister David Cameron, George Osborne and Jeremy Corbyn, and of course Uxbridge and South Ruislip MP and Mayor Boris Johnson.

It opens with a baby Boris jumping up and down on a climbing frame shouting "I'm Prime Minister!", while a teeny George Osborne talks about his '"necomonic plan".

Meanwhile, Labour's little Corbyn chairs a crisis meeting in the nursery, after he found a hand-scrawled sign which reads "Jerimee wears silly clothes" in the toilets.

"Everybody's saying bad things about me and it has to stop," he complains.

A sign saying "kick me out" is taped to his back as he walks away from the camera.

As the lead up to the London Mayoral Elections gets closer, classroom arguments go from showing disputes at the top of the political parties, right through to mini candidates Zac Goldsmith and Sadiq Khan bickering in a sandpit over whose house is better.

Classroom arguments go from trident bickering to Cameron kicking over plant pots so fracking can be carried out there.

The clip then closes with a grown-up saying the Green Party don't get involved in such childish playground-politics.
