This Violet black-legged robberfly (Dioctria atricapilla) seems to have caught a Leptogaster by the hindlegs (or the Leptogaster chose the wrong target and had the tables turned...) - but what is the Leptogaster sp? cylindrica or guttiventris are possible in the UK? I've never seen asilids holding prey by the back feet before, but Leptogaster seems to have long well articulated hind feet ( a bit like Hanging flies - bittacid Mecopterans in the US which catch prey with their hind feet ) which makes me wonder if the Leptogaster is hanging on rather than the other way round!
