A new social media post on Sunday features the prime minister's face alongside the tagline: "Do you think your child's school should be safe? Rishi Sunak doesn't."

It comes as the government continues to investigate the extent of problems with crumbling concrete, also known as reinforced autoclaved aerated concrete (RAAC).

Dozens of schools have been affected, with many unable to reopen in the coming days as they had planned.

The Labour Party has gone on the offensive over the concrete chaos, but its latest attack ad could cause controversy.

Previous iterations have accused the prime minister of failing to send child sex abusers to prison, being soft on gun crime and suggesting thieves should not be punished.

One of the ads also took aim at Mr Sunak's wife Akshata Murty and her previously held non-dom tax status.

Speaking on Sky News' new politics show Sunday Morning With Trevor Phillips, Jeremy Hunt said more schools and other public buildings with structural problems could come to light in the coming weeks.

But he pledged that the government would do "what it takes to make sure that children are safe" and that as chancellor he would "prioritise spending money to sort out these problems where that needs to happen".
