No.
This is not a power struggle generated by a bunch of egotists, but a very real, deep -seated concern about Theresa May's incompetence.
She is failing to deliver the Brexit agreement she promised when she took office, her worst mistake being conducting the negotiations herself. She has agreed to concession after concession, received nothing in return, whilst systematically undermining Brexit ministers appointed for just that job.
Parroting 'this is the best deal we will get' is not good enough. After failing to honour her promise to hold a vote she should have withdrawn to No. 10, with the remnants of her cabinet, and forged a policy for a no deal exit, which is what she promised, until she halted the preparations in March.
Instead of which she raced around Europe exposing herself to yet more humiliation from the EU, who are playing her in exactly the same way as they played Ireland, Greece, Denmark and any other countries who are concerned about the form this organisation is taking.
