Private pensions to remain excluded from someone's estate for Inheritance Tax

We believe the inheritance tax was originally a tax for the rich only, those who had mansions, estates and land, however due to frozen limits, fiscal drag etc, it now brings even low/middle earners into paying Inheritance Tax, especially if the private pension is included in their estate, as planned for April 2027. We think it also disproportionately affects single parents or unmarried couples due to the limit for tax free allowances. A person with just an average house, who saved for retirement could end up with a huge tax bill.
