I think you are talking about (left to right) :
Rob Oldaker, Managing Director of MG Sport & Racing (in glasses),
Ffiona Welford, Motorsport Associate of MG Sport & Racing (with blonde hair)
Warren Hughes, Driver of one of the MG Sport & Racing entered MG ZS EX260 Touring Cars (signing something)...
...not sure who the lad in the foreground or the chap with the baseball cap is though! Or the two chaps who have been 'Tango-ed' in the background!
