He said: “Few people might have appreciated just how much was at stake here.
“This April, the state pension will increase by 2.5 percent from £175.20 to £179.60 a week. While £4.40 extra a week may not look huge, losing all future increases really adds up.
“With many people living 20 or more years after state pension age, any form of inflation proofing is highly valuable, with the triple lock particularly so.
“An inflation linked state pension of £175.20 a week is worth around £327,000 whereas one that doesn’t increase is worth around £188,300 which is £138,700 less.”
