Labour revived its controversial attack adverts campaign against Rishi Sunak yesterday, claiming he did not think that school buildings should be made safe.

In a provocative and misleading post on social media, a smiling picture of the Prime Minister with his trademark signature is accompanied by the words: ‘Do you think your child’s school should be safe? Rishi Sunak doesn’t.’

Labour claimed the advert was justified because funding for school rebuilding fell by almost half during his time as Chancellor. 

But a Tory source described the advert as ‘pathetic’, pointing out that classrooms were being shut as a precaution in order to ensure that schools are safe for pupils to return this week.

Critics also pointed out that the Government has acted far quicker than the Labour-run administration in Wales, which only started a new survey of schools with potentially dangerous concrete last week.

In the run-up to the local elections in May, an opposition advert claimed that the Prime Minister was happy for convicted paedophiles to walk free

A Conservative Party spokesman said: ‘Labour were warned about this when they were last in office and did nothing; they ignored the issue in opposition; and now it’s in the news they have decided they are interested.

‘In the meantime, in Labour-run Wales they are recklessly sending students back to school without checking they are safe, leaving parents in the dark.’ Yesterday’s attack revived a notorious campaign run by Labour earlier this year.

In the run-up to the local elections in May, an opposition advert claimed that the Prime Minister was happy for convicted paedophiles to walk free.

It featured the words: ‘Do you think adults convicted of sexually assaulting children should go to prison? Rishi Sunak doesn’t.’

The controversial advert prompted concern even within Labour ranks.

Shadow Home Secretary Yvette Cooper declined to endorse the campaign while former Labour home secretary David Blunkett told how the ‘gutter’ tactics left him ‘close to despair’.

However party leader Sir Keir Starmer was defiant, saying he would ‘stand by every word’ and would ‘make absolutely zero apologies for being blunt’.
