The cap was lifted
The maximum permitted contribution from RTB receipts to replacement affordable housing has increased from 50% to 100%.

A recent change that evidently hasn't done much yet to undo all the damage of previous decades.
It's well known why the Tories loved the idea of selling off council houses and your position seems quite bizarre (David Cameron wasn't a Tory?) however we are taking this thread off topic, so I will make this my last post in this exchange:
"At the 2011 Conservative Party Conference, David Cameron proposed to increase Right to Buy discounts in order to revitalise the housing market and generate receipts which could be spent on new housing. Social housing professionals expressed concerns over the proposal.
As of 2 April 2012, the Right to Buy discount was increased to a maximum of £75,000 or 60% of the house value (70% for a flat) depending on which is lower. In March 2013, the maximum discount in London was increased to £100,000. The maximum right to buy discount increases each financial year in line with CPI as at the previous September.
The aim of the scheme is, for every additional home sold, a new home will be built for 'affordable rent' at up to 80% of market rent, aimed at maintaining the level of affordable housing while also increasing the number of properties available for those on the waiting list. The five year tenancy criterion will remain, and should the property be sold within the first five years of the original sale, part or all of the discount will be required to be paid back.
The Housing and Planning Bill 2016 extended right-to-buy to housing association tenants."
"Criticisms
The Right to Buy scheme has been criticised for the following reasons:
Speculating investors were able to buy up council properties through deferred transaction agreements, hastening the rise in property costs;
Commercially and socially valuable council assets were sold at below their market value or replacement cost, which can be seen to be an imprudent waste of public money;
The remaining stock of council housing was concentrated in undesirable areas with little employment opportunity, further isolating and stigmatising the tenants.
A report published in January 2013 by London Assembly member Tom Copley, From Right to Buy to Buy to Let, showed that 36% of homes sold under Right to Buy in London (52,000 homes) were being rented by councils from private landlords, leading to criticisms that the scheme "represents incredibly poor value for money to taxpayers" since it "helped to fuel the increase in the housing benefit bill, heaped more pressure on local authority waiting lists and led to more Londoners being forced into the under-regulated private rented sector". A survey in 2013 showed around one third of Right to Buy houses were now owned by private landlords, while the son of the late Ian Gow (Thatcher's housing minister) owned some 40 houses.
In 2015, Alan Murie concluded that "the proposed extension of right-to-buy could not easily be reconciled with the independence and charitable status of housing associations" and that "extending the right-to-buy to housing association tenants revived a previous Parliamentary debate and raised questions about the legal position of charities and the risks faced by housing associations and their funders".
A 2017 BBC survey of council areas where waiting lists were rising showed the councils had bought back houses they had been forced to sell, sometimes at many times the original price. Housing charities criticised the lack of investment in affordable housing."
