The Tories today warned white working-class boys 'don't need another Labour quango lecturing them' as the Government overhauls its equalities agenda.
Bridget Phillipson, the equalities minister, is expected to announce plans to place social class on a par with sex, race and disability for the first time.
Her reforms are also set to establish a new Whitehall unit to improve outcomes for lower-income families.
Sitting within the Office for Equality and Opportunity, it is thought the new unit will impose a socio-economic duty on public bodies.
This will legally require them to consider how to improve the lives of lower-income families and change the way Government assesses areas of deprivation.
The Social Mobility Commission, launched in 2010 and previously known as the Social Mobility and Child Poverty Commission, is expected to close as part of the plans.

It was established to assess progress in improving social mobility in the UK and to promote social mobility in England.
Conservative MP Joy Morrissey, the shadow equalities minister, criticised the reported plans and warned against pushing 'more bureaucracy' on organisations.
She said: 'White working-class boys do not need another Labour quango lecturing them about identity and privilege.
'A socioeconomic duty will simply drag businesses and public bodies into yet more bureaucracy, hamper growth and encourage class warfare instead of aspiration.
'Socialism does not create prosperity or equality; it divides people into competing groups and leaves everyone poorer.'
Ms Morrissey added the Tories would 'abolish this duty and restore meritocracy to the heart of public life'.
The establishment of the new unit, first reported by The Times, will be the first time a government has specifically created a dedicated Whitehall team to reduce class inequalities and discrimination.
It is expected to sit alongside similar units covering race, gender, LGBT and disability rights.
A Government source told the newspaper the new unit would be a 'centre of excellence' for data analysis on class, socioeconomic background, public services and outcomes.
Some of those Cabinet Office officials who currently support the work of the Social Mobility Commission are said to be transferring to the new unit.
