The 47.5K at 14.37pm was cancelled by the -47,500 at 14.37pm higher up.
The 50K and 72.5K trades were filled during the day so they don't really have a fixt time - the (T) shows they are 'protected'. A buyer might want 100K and the mm's say we can get you 50K and we'll try to get the rest through the day. You might then get all or part of the rest.
I'd say the 72.5K @ 110p is a buy - that's why there was an MM buy at 110p earlier in the day.
I'd say the 50K at 109p is a sell that went to fill that 72.5K buy, probably the guy that has been selling 25K frequently. Might have cleared him out and that's why we are on the up.
I reckon that 72.5K buy was put in yesterday and that's what made these move then imo and why we saw no big trade yesterday.
