Rita Ora attracted hundreds of complaints from BBC viewers after she appeared on The One Show wearing a plunging suit jacket.

The 24-year-old, who was promoting the launch of The Voice UK with fellow coaches Ricky Wilson, Tom Jones and will.i.am, outraged viewers with her cleavage-revealing outfit.

Nearly 400 people complained about it on the Corporation’s Points of View message board online.

One posted: “I don’t want to see her boobs hanging out on a family programme. I find it quite disgraceful.”

Another wrote: “I am no prude but I found it totally inappropriate.”

The BBC has so far received 424 complaints regarding Rita Ora’s outfit.

"The One Show allows guests to choose their own attire and pop stars often opt for something glamorous or striking," a spokesman added.

“We didn’t feel that Rita’s outfit would be outside of most viewers’ expectations of that of a major pop star, but we appreciate that tastes vary.”

The Voice starts on BBC One on Saturday 10 January.
