THE Liberal Democrats say an estimated £50 billion "remain bonus" will allow them to invest billions in schools and new teachers.

The party said a windfall from stopping Brexit would give them £10 billion to spend on schools and hire 20,000 more teachers by the end of the next Parliament.

The party claims the economy would be 1.9 per cent larger by 2024-5 if the UK stays in the EU rather than leaving on the terms of Boris Johnson's withdrawal agreement.

It said staying in the EU would generate £50 billion over the next five years, taking into account money saved from the UK not paying the £39 billion "divorce bill".

The Lib Dems plan to spend most of this money on education. The party referred to figures from the National Education Union, which show that next year schools in Brighton’s Kemp Town will have seen their budgets slashed by £2.2m since 2015, equivalent to a cut of £277 per pupil.

The party said across the Kemp Town constituency, 85 per cent of schools have seen their spending power cut since 2015.

The Lib Dems plan to increase teacher numbers, raise teachers' starting salaries to £30,000, guarantee them a pay rise of at least three per cent a year over the next Parliament, and provide more support for children with special educational needs and disabilities.

Beatrice Bass, Liberal Democrat candidate for Hove and Portslade said: “The Conservatives have cut school funding to the bone and children in Brighton and Hove have paid the price, especially those with the most complex needs.

“Parents tell me that without the dedication of their schools’ heads, teaching team and community support, the impact of these cuts would be far larger. They have had enough and welcome the Liberal Democrats’ plan to properly invest in our schools and a brighter future for our children.”

The £50 billion figure is based on the Institute for Fiscal Studies' estimates, which assume that a Labour-led coalition takes power, renegotiates a Brexit deal, and holds a second referendum where remain wins out.
