Proposed changes to the way schools are run revealed in the Chancellor’s Budget have been branded as an “ideological attack on the education system".
The change could lead to a longer school day and possible make studying maths compulsory until the age of 18.
Ms Cadbury said: “This is an ideological attack on our education system, and one where there is a risk that schools have no accountability to parents and children.
“Schools in London are also set to lose funds as the government changes the national funding formula for schools. This could have a hugely detrimental effect on our children’s education.
“Rather than bringing the rest of the country up to London’s standards the Chancellor is creating a race to the bottom in terms of education funding.”
Among the other ‘disappointing’ announcements were the continued cuts on working families, and the government’s support for multinational companies.
'Cuts to essential services'
Ms Cadbury added: “The government is more concerned with cutting local authority grants and those very services that families on the breadline so desperately need.
“Whilst small businesses will no doubt welcome the proposed business rates cuts to be introduced next year, the new link between rates and local spending will mean yet further attacks on councils....and will mean more cuts to essential services such as rubbish collection, roads, social care and libraries.
“While the Chancellor cuts regulations for banks and offers low rates on taxes for multinational corporations, local authorities are bearing the brunt of the cuts.”
However on the opposition side, Hounslow conservatives welcomed George Osborne's announcement as a “Savers, Strivers and Surprising” Budget.
They praised the new lifetime ISA for under 40s to be introduced from April next year which allows people to save £4,000 a year and receive a £1,000 government bonus and the rise in standard ISA savings to £20,000 tax free.
A freeze on fuel duty for the sixth year and the benefit to 600,000 small businesses paying no rates next year as a result of raising the thresholds, were also welcomed.
Suggestion government not helping working class is 'bonkers'
Leader of the Hounslow Conservatives councillor Peter Thompson said: “Whoever said the government is not helping working class people is just bonkers and in denial.
"[They are] helping those saving for their home with the Help to Buy Scheme and Help to Buy ISAs as well as increasing the personal allowance before tax.
“In addition, we have protected the National Health Service and police budgets meaning spending has increased year on year and local community policing has been protected.”
He added: “Low-paid workers too have received a boost from the Government under a new Help to Save scheme (in 2018), where low paid workers who put aside savings could receive £1200 bonus over four years.
“This will help around 3.5m workers on tax credits or universal credit and if they choose to withdraw the money, they can do so without incurring any penalties.”
