The Prime Minister Boris Johnson met pupils at a Suffolk primary school this afternoon – and the subjects included Ken Livingstone and heads on spikes.

At around 2pm, he visited Abbots Green Academy in Bury St Edmunds.

He joined a group of pupils in an activity sorting pictures of London into past and present.

Mr Johnson held one black and white image aloft and suggested "past?".

One pupil agreed and said it "looks dirtier", to which the Prime Minister replied: "That was when Ken Livingstone was running it."

Referring to a photo of London Bridge, Mr Johnson told the youngsters: "You know what they used to do? They used to stick the decapitated heads of the enemies on spikes."

He also visited a classroom where children were mummifying pumpkins with salt, and another where they made firework collages.

He then met a small group of journalists, before heading off to his next engagement, which is outside Suffolk.

Earlier, he had been at Addenbrooke's Hospital in Cambridge.

Politicians are gearing up for six weeks of campaigning before we go to the polling stations six weeks today - and this region is likely to feature firmly on politicians' radars.

Mr Johnson received a boost today when it emerged that The Brexit Party is considering withdrawing candidates in many seats in a bid to avoid splitting the vote and allowing pro-EU candidates to win.
