A BUS company has warned passengers to expect delays as schoolchildren take to the streets as part of further youth climate strike.

Past Youth Strike 4 Climate events have seen hundreds of schoolchildren march through Brighton demanding further government action on climate change.

In an event page on Facebook, organisers said: "Join us at Churchill Square from 11am to demand government action on climate change once again. We will not stop until we have climate justice for all."

It has been called the "one year anniversary strike".

Brighton and Hove Buses warned the strikes could cause disruption to its services.

A spokeswoman said: "We're aware of another Youth Strike 4 Climate Protest due to take place in central Brighton today, between 11am and 3pm.

"At this stage, we're unable to confirm details of the route nor how this will affect services.

"Keep an eye out here for updates during this time."

Shortly before 11.30am the company updated passengers.

The spokeswoman said: "Due to the Youth Strike 4 Climate Protest, all BH6 services are diverting via Montpelier Road and Seven Dials to and from the station - both ways.

"All BH7 services towards the Marina are operating from the station via Upper Gloucester Road, Buckingham Road and Dyke Road onto North Street."

Services were reported to be "back to normal in the Brighton Station area" at 11.50am.

Protesters are now reported to be outside Chruchill Square shopping centre in Western Road.

Activists are holding signs with handwritten messages including ones which demand "climate action now".

Green councillors including convenor Phelim Mac Cafferty, Marianna Ebel and Hannah Clare, Martin Osborne and Sarah Nield have joined young protesters outside the shopping centre in a show of support.

Brighton Pavilion MP Caroline Lucas also sent her support to striking students and referenced further youth strike events taking place across the country today.

She said: "Sending love and solidarity to the thousands who’ll be taking part in climate strikes today.

"Your leadership on the climate emergency has put politicians to shame.

"In the year when UK hosts the UN climate summit, it’s more important than ever."

Hundreds of similar demonstrations were organised during 2019.

A spokesman for the UK Student Climate Network said: "We are a group of mostly under 18s taking to the streets to protest the government’s lack of action on the Climate Crisis.

"We are mobilising unprecedented numbers of students to create a strong movement and send a message that we are tired of being ignored.

"Throughout 2019 we’ve organised more than 850 demonstrations, including the September Global Climate Strike that saw more than 300,000 people take to the streets across the UK.

"We’ve raised the bar and elevated climate breakdown high on the agenda, but we know there’s still so much to do.

"We need urgent and ambitious action on climate which is why we’re calling for a Green New Deal."
