Western Isles MSP Alasdair Allan has called on proposals to stop free TV licences for over 75s to be abolished.
The SNP politician has called for the Conservatives to keep to their election manifesto pledge and fund the BBC to make sure that this benefit remains feasible.
The BBC has launched a consultation on the matter, which will run until February 2019.
There are over 447,900 individuals in Scotland over the age of 75. Over 3,000 live in the Western Isles – each saving £150.50 a year under the present system.
Mr Allan said: “After years of Tory austerity, and the deep financial uncertainty that Brexit is causing, the last thing that our elderly population need is to have an extra £150.50 added to their household bills.
“With the BBC consulting on the Over 75s free TV Licence, considering whether it should be watered down, or scrapped altogether, the benefits that this policy brings to older people must be taken into consideration.
“Our older generation must always be treated with dignity and respect. Over 3,000 of my constituents are over the age of 75, and thus eligible for this benefit.
“Having access to television can provide an important window to the world, for those who suffer from loneliness, and live a long way away from their families.
“The UK Government need to explain why they are breaking their promises on this, and move now to ensure that our elderly population do not suffer from this ill-thought out proposal.”
