The headline is a tad misleading. The current Conservative government has no new plans at all for the SPA. The Centre for Social Justice, a conservative think tank, has produced a report recommending that the SPA be raised to 70 by 2028 and 75 by 2035. Whether or not the government will take any notice, I do not know.
Decisions on the SPA are based on reports by the Government Actuary. The last one was in 2017, which resulted in the increase to 68 being phased in over the years 2037-39 rather than 2044-46.The next report is due in 2023 - they are made at 6 year intervals.

I don't expect any changes until 2023. My best guess would be that the SPA will be raised to 70 from 2040 onwards. Unfortunately we have an aging population and there are limits on what kind of burden you can impose on the working population.
P.S. Isn't Ros Altmann a bit of a plonker; “There must be a facility for those who can’t work to retire earlier.” Really? What bloody difference does it make?
