Rani's warm style complements the sharper end of Barnett's presenting - not that women need all be hot water bottles, but it bodes well for the gentler Friday edition, as well as providing a reassuring listen when hosting Saturday's 4pm round-up. There's a bit of everything on her CV, but Rani goes in up to her waist rather than simply dipping in a toe.
"I've always been a fan of Woman's Hour and admired the presenters who have hosted the show previously, so I can not wait to become part of it myself", she said. "What an honour and what a way to kick off the weekend".
Mohit Bakaya, Controller of Radio 4, says: "I want Radio 4 to continue to seek ways to better reflect and be relevant to the audience across the United Kingdom, and Woman's Hour has a special role in this when it comes to subjects and stories that matter to women".
"Woman's Hour has a special role in this when it comes to subjects and stories that matter to women", he added.
Rani is a regular presenter on BBC Radio 2. At the age of just 14 she had her own radio show on Sunrise Radio in Bradford.
WATCH: Anita Rani talks kindness for HELLO! She brings entertainment experience at Channel 5 (and being on the other side of the camera during her time on the 2015 series of Strictly); consumer journalism insight from presenting Watchdog, rural affairs from Countryfile - thus neatly avoiding any grumbles about the Beeb's metropolitan focus - and documentaries.
Barnett and Rani are excellent journalists, but something else makes them a valuable addition to Woman's Hour.
Barnett became Woman's Hour's main host in early January after Jane Garvey and Dame Jenni Murray chose to quit.
Okafor had been due to speak to Barnett about the Me Too movement but tweeted saying she had decided not to appear, after overhearing the presenter "talking shit about me to the producers".
