The PG Tips and Lipton tea brands could be sold by consumer goods giant Unilever because they are falling out of favour with the public.
The firm is reviewing its tea business amid a slowdown in sales as more consumers switch to the herbal variety.
It is part of efforts by chief executive Alan Jope to refocus the firm and concentrate on fewer brands.
The announcement came as Unilever announced its slowest quarterly growth in a decade.
The firm said its sales in the final three months of 2019 were up just 1.5%. However, it said it expected a stronger performance in 2020.
Unilever said it would look at “all options” for the tea business, including a partial or full sale.
