The way I understood it was that the new £140 pension would incorporate various 'extras' that are claimed at present and 'make up' the basic pension.
Few pensioners live on just the basic.
In fact the pensioners who will not qualify for the £140 might eventually end up better off!! Time will tell, once all the 'spin' about this so-called increase has evapourated. But perhaps I'm just being cynical!!
