Why bring in another camera when you already have 7 covering every possible angle you can imagine in your wildest dreams?

Taking a guess the start of the new financial year has enabled the additional resource.

Maybe the justification was that with past faults with the cameras they want to mitigate the risk one of more failing during the programme, given they often have high profile political interviews. At least if one or more robotic cameras develops a fault the manually operated camera can cover those shots.
