So, she has to save at least £360m to get back to square one pre-crisis. In fact probably more due to lost customers. And they've barely sorted out the move from one bespoke system to another. Local team probably really pissed off and now expected to 'perform' even better while dealing with offshore teams that don't really give a shit.
