Earlier, in an interview with the Daily Telegraph, Mr Webb highlighted that some of those claiming a married person's allowance had never been to the UK, and this was unfair.
And since 1991 the National Conference of Commissioners on Uniform State Laws, a group dedicated to rationalizing and harmonizing state laws, has urged states to make this the default for a marriedperson with kids (but no children from a previous marriage) who dies intestate.
As part of this change, derived entitlement to the basic state pension - where someone receives a married person's pension or a widow's or widower's pension based not on their own working life but the National Insurance record of their spouse or civil partner - will also go.
