BobTheDuvet sorry if I didn't make the reasons for my sceptiscism clear. A PP probably explains my point better,
Unless more info comes out, nobody else SAW what was going on and to be able to hear clearly what was said through 'Victorian' house walls that tended to be quite thick, is more than a bit suspicious. Anyone can throw a few plates around, stamp about and shout.
The idea that two media trained people would so totally forget themselves when one of them is in the running to be the next PM and the other played a part in getting them there seems somewhat unlikely. Not impossible but unlikely.
You are correct that the Guardian have not used the word alledged but then they themselves have not asserted it is Boris and Carrie that can be heard on the recording. Those claims are reported as being made by the neighbour. All we can be reasonably certain of is that an argument took place at the address where they live and the recording evidences involvement of a male and female.
To be very very clear I do not think that well educated, professional women are immune to domestic violence but on the evidence that we have it is a stretch to assume that is what is happening.
