This is going to be either hard-going or side-splitting for you, depending on your point of view.
I could only watch it once, but from memory this is the nuts and bolts of it (in case the sight and sound of her is more than you can take) :
According to Ms Eagle:
Jeremy has lost the confidence of the members of the Labour Party in the country. Well, on the other hand, I'm not so sure about that, Angela;
She has strong Labour principles, (which is why, among other right wing policies, she voted for the Iraq war, and against the Chilcot Inquiry);
Her constituency party backed Corbyn, but according to her this was due to "disruptive elements" in the "new" membership. She has, she says, more support that it seems... However, according to this article, the vote of her constituency party was 40 for Corbyn, O against and 4 abstentions. So it seems there are rather a lot of parvenus and no possibly 4 "Longtermers" (who didn't vote against Corbyn) on her executive, or she's got that a bit mixed up;
She says Labour Party rules demand that Corbyn get 50 nominations regardless of the fact that he is the sitting leader (and was roundly elected with just shy of 60% of the vote less than 1 short year ago), but that is certainly open to debate (as can be seen above extract of the rule changes);
When Peston challenges her on this she says that they will decide on the rules on Monday. Damn it. I thought rules were rules;
She goes off on a tangent trying to recruit new members (who presumably she images will back her... and Peston lets her), and then she blames Jeremy for the fact that England (and Wales) voted to leave the EU;
She refuses to answer a question about whether, should she lose to Corbyn, she will serve in a shadow cabinet of his should she be asked to;
She also refuses to answer if she would lead Labour into a 2020 General Election, saying that she is sure that there will be an election soon (despite the fact that Theresa May has said that, if she wins the prime ministerial election currently being played out by the other bunch of inward looking self servers, as she almost surely will, there will be no election);
Angela then wants to talk about how living under the Tories has been a tragedy for the poor, which is perfectly true. She doesn't mention, though, that many of the harsh things that the Tories did originated in Blair or Brown's governments... Anyone remember ATOS for example?
It strikes me that Peston may or may not have been a reasonably good reporter on financial matters for the BBC, but he's a relative lightweight when it comes to political interviews. Unless, of course, he favours the wing of the party, like DAME Margaret Hodge and LORD Kinnock, that wants to see the back of the kind of Labour that Jeremy Corbyn represents, and one more in keeping with their own elevated and aristocratic status.
