The tweet is about her and Annita.

I'm assuming Yalda, Lucy, Christian, Matthew and Maryam will be off air for the month of March while they prepare for launch date 3rd April. Which means we'll see much of Martine, Annita, Ben, Shaun etc in the mean time, and then, after that is, well is anyone's guess...

The BBC can't ditch all of the NC presenters who are left. I can't imagine the 5 "chief" presenters doing more than 4 or 5 days a week, so other presenters will be needed for weekends and potentially Fridays as well. 
Also, if Christian Fraser still stays on The Context at 9pm weeknights, then potentially an extra presenter will be needed from somewhere for a daytime shift.
