No specific aircraft has been mentioned but it will be high wing, piston or Diesel powered and have an operational crew of two. It is required to have a retractable un- dercarriage. Those details alone remove numerous airframe options from the competition. The role is to be overt, not covert, so we can expect it to be dark blue and yellow like the helicopters and the long departed Cheshire Islander, and it will be an eyes out of the cabin

Entering the arena of speculation the aircraft options appear to be either the Tecnam[rumoured to be too small and non-IFR] and the Vulcanair P-68R which is a variation on the type they are currently trialling.
Not quite sure how they will assess the capability of operating safely down to 500ft......
This suggests it the Vulcanair:-
