Len Goodman has blasted plans to scrap free TV licences for pensioners.
The 74-year-old star has described television as a "precious window to the modern world" for many elderly people who have become lonely in their old age, after potential proposals were unveiled to make over-75s pay for the privilege.
He told the Daily Mirror newspaper: "For some older people telly is their only companion. It's what breaks the day up when they don't see anyone and keeps them in touch with the news.
"TV provides entertainment and educational value for older people.
"But it's a much greater source of comfort and companionship to those living in loneliness and those who are housebound. For the chronically lonely TV must be a precious window to the modern world."
Former "Strictly Come Dancing" judge Len added it would be a "worry" for may pensioners, who might not be able to afford the £150.50 fee - which will rise to £154.50 per year in April.
Len is backing Age UK's Switched Off: Save Free TV for Over-75s campaign, and the star - who is an ambassador for the charity - has spoken out about loneliness for older people.
He added: "Life is one big rush and no one has time to stop and chat. But a friendly natter can make an enormous difference."
Len previously hinted at working towards retirement, opening up on the most recent season of US show "Dancing With The Stars", which finished in November.
He said at the time: "This may be my last season. It's the end of my contract and they may not what to have me any more. They might have had enough of me.
"I don't want to retire totally but I'm quite happy doing nothing - reading a book and pottering in the garden."
