There was a discussion here not long ago about where Labour had broken manifesto promises.
To be fair to Starmer, he made it perfectly clear he would not be raising Tax, NI, or VAT.
Only, the last part, VAT, is a lie - this is a broken promise, as he did raise VAT for children's education.
This is a direct broken manifesto promise. In the manifesto, he did not single out that a certain group didn't count, he made it clear. In fact, he told everyone that he was making it clear. No raising of Tax, NI, or VAT.
Whether you disagree in education being taxed/private schools etc, the debate was around if any manifesto promises were broken, which clearly they were.
