Anne Robinson has presented the Weakest Link since 2000
The BBC has received complaints after Anne Robinson asked a contestant to feel her breasts during a celebrity charity version of The Weakest Link.
TV wine-taster Olly Smith felt Robinson's breasts after referring to the 63-year-old presenter as a "full-bodied, expensive red".
The BBC stressed it was a "playful and light-hearted" exchange.
But 16 people complained about the incident, which was broadcast at teatime on Saturday.
The programme was watched by 5.5 million people, the BBC said.
It featured 10 contestants from the world of food and wine, including TV chefs Sophie Grigson and the Hairy Bikers.
The exchange came after Robinson told Smith - who appears on Saturday Kitchen and Richard and Judy's Wine Club on Channel 4 - that she did not like being called "full bodied".
She then invited Smith to feel her breasts, who declared them to be "absolutely fantastic".
The Weakest Link has been a hit around the world since it first aired in 2000.
It moved to BBC One in February to fill the slot left by long-running soap Neighbours, which moved to Five.
