Probably a medical diversion. Would be my guess.
The other delays are either:
a) Residual delays rattling around inside the system.
b) VS are an aircraft down due to defects or MX.
ISTR there are 7 LGW/MAN config 744s, and on an average day, 6 of them need to be flying, and there are occasional days during the peak periods (e.g school hols) that all 7 need to be working.
If VS are one aircraft down, then the usual thing would be to 'step up' arriving aircraft at LGW to depart sooner than usual (send them out on an earlier flight than they would normally depart with).
Of course, stepping up A320s is one thing, a 450-500 seat airplane is a non-trivial affair.
The room for manoeuvre - to shuffle aircraft around to minimise delay - is limited if VS are an aircraft down, and further limited by the BGI operating from LHR, as this has taken one of the LGW fleet over to LHR.
Substituting one of the LHR fleet in is probably a non-starter, as the LHR 744 fleet is being worked particularly hard at the moment anyway - it's currently doing all the JNB flying, which takes the aircraft away for 2 days. Also the new LHR config isn't particularly suited to LGW routes.
Of course, all the above is a load of postulation.
