She left at the end of April, so her tenure was far longer than I remember (only 3 months less than Liza Tarbuck).
I can see what they were doing with Sharron - a Gaby-esq mumsie figure, but gosh she was so awkward. She just wasn't right for the job, and I can't believe she chose to commute every day from the Cotswolds to Bow.
Her last day was 2nd May, the day after the election. Although for the last few months she was barely there, and I always wonder if they realised from day one that she wasn't working out, given how quickly they got Denise into the house. I know they said it was too dark to see anything from the helicopter, but they'd have known that when they started it.
The short-lived TV magazine The Box did a bit about Sharron during her reign of terror, I remember it said "Coming up next: A woman reading off a clipboard" and said that all she ever really did was read stuff off that, in a tone that sounded like she was reading her shopping list ("OK, I've trailed that item, three more items to do"). It also said that Rick Adams had clearly sensed the void where her presence should have been so just talked and talked and talked to make up for it.
