Actually here is what Angela Rayner, Shadow Education Secretary, wrote about grammars:
"They entrench division and separate out children at an early age.
The evidence shows that grammar schools overwhelmingly benefit those from more affluent backgrounds. This has absolutely nothing to do with academic ability and everything to do with background and wealth.
Grammar schools are about stigmatising children, not on the grounds of their ability, but on their background.
Sowing division like this, and contributing to a system that fails to promote social mobility and help those from low and middle income backgrounds, is about as far from One Nation as it gets.
For Theresa May to pose as a One Nation Tory, and then propose a policy that will divide our children into successes and failures at the age of eleven, really takes some nerve.
The Prime Minister cannot get away with this.
David Cameron said that those in his party who wanted more grammars were "splashing about in the shallow end of the education debate."
He was right. We need to focus on helping EVERY child to get a world-class education in EVERY school in this country. We must ensure that every single child can go as far as their ability and their aspirations will take them.
That's what a One Nation education policy should be about.
To focus instead on opening new grammar schools, to splash about in the shallow end, is to turn your back on the majority of children in this country.
It is a diversion from the real issues that face our children.
And it is bred from ideology, not the best interests of our children.
It means ignoring the fact that those from less affluent backgrounds have the ability, but do not have access to the resources, that would tilt selection in their favour.
It means ignoring children who develop later in life, but are no less able than their peers.
It means stigmatising our children as "failures".
Time and again grammar schools have failed our young people. From admissions to outcomes, those from the least advantaged backgrounds benefit the least from grammar schools, while the most affluent benefit the most.
That's why Tony Blair stopped the expansion of grammar schools. That's why Labour believes in doing all we can to help every single child in this country, whatever their background, to succeed.
That's what it means to believe in aspiration, and to promote social mobility.
Bringing back grammar schools is turning back the clock to a mythical golden age, to a romantic view of the past in which grammar schools were the great engines of post-war social mobility.
Even when the evidence says different.
Theresa May, and her new Education Secretary Justine Greening, say they will place social mobility at the heart of everything they do. Introducing grammar schools does the exact opposite.
I hope wiser counsels will prevail in today's Tory Party.
And that genuine One Nation Tories will pursue a One Nation education policy, working to improve opportunities and outcomes for EVERY child."
