It was also revealed that about 115,000 pupils will move up to secondary education next month, at least two years behind their classmates.
It also showed that more than 50,000 of the flops were so poor in their studies that they were not even given a grade for reading.
The figures that were reveled on Tuesday, Aug 4 are a blow to Labour's pledge on education.
Only 80 per cent of 11-year-olds passed at English, which is one per cent down from last year.
Schools Minister Diana Johnson made an astonishing defence of kids who failed to hit Level 4 - the grade expected of 11-year-olds.
"Let's recognise that a level three child can still read," the Sun quoted her as saying.
Shadow schools secretary Michael Gove blames Labour for the lack in proper education.
"This is proof that Labour, elected on a platform to raise education standards, has failed to deliver. Weakest pupils are being failed most," he added.
