Angela Rayner will talk about ending academy trust “fat cat salaries” when she addresses the Labour Party conference tomorrow.

In an on-stage interview with Guardian editor-in-chief Katharine Viner, the shadow education secretary this afternoon listed a series of principles that she hopes to set out, based on conversations she had during the consultation on the party’s planned National Education Service (NES).

She said: “One is, it’s about collaboration and not competition – that’s quite important.

“They want money in the system to be valued. They want it to be a public service run for the public good and not for private enterprise.

“They want to end fat cat salaries and trusts where there seems to be no accountability for the monies that go there.

“They want a broad-based curriculum that allows every child to fulfil their potential.

“They want life-long learning so everybody can be educated and can enjoy education”.

Ms Viner asked Ms Rayner “what exactly” the NES is.

She responded that it was “cradle till grave, genuine, based on the National Health Service – public service about ensuring that everybody, regardless of their age or their ability has the opportunity to learn free at the point of use.

“So it’s about much more than just primary or secondary education, it’s much more than tertiary education, it’s about genuinely building communities and giving people opportunities.”

As reported by Tes today, a document from the party’s Early Years, Education and Skills Policy Commission about the NES revealed that the party was exploring how to make academies answerable to their local communities.
