I was one of the 20 writers fortunate enough to make the shortlist for this competition. I was interviewed for a place in the development pool, however I wasn't one of the 6-8 people they selected (the other folk that make up the 15 in the pool were the winners of other competitions/talent searches).
Sally's inclusion has understandably upset some people, but if you actually think about the logistics of the subterfuge she/the BBC is being accused of then the argument about it being a fix quickly disintegrates.
There were over 2,100 scripts submitted, which were read by several script readers. To get to the shortlisted 20, your script would have been read by at least 3 different people at various levels of the writersroom. So Sally's script must have been great.
If anything I'd argue that the odds were actually against her at the interview stage. The BBC is extremely sensitive to bad press, and they would have been well aware of the potential backlash from this (shown by the fact that they opened their announcement of the winners with an explanation of Sally's inclusion) and the potential for lasting damage to the integrity of the Writersroom.
So the fact that they took such a big risk shows that Sally Stott must be an extremely talented, funny writer who deserved to be a winner of that competition. I didn't quite make the grade. Fair enough - I'll just write something better next time.
