Quite possibly, but when it comes to helping the tories poor old compo leaves everyone else in the shade! and now this:

Jeremy Corbyn's top aide instructed party officials to compile a dossier setting out how Labour's highest disciplinary body could be challenged, leaked emails have revealed.

Mr Corbyn's chief of staff, Karie Murphy, said it was "absurd"
the National Constitutional Committee (NCC) - which operates independently of the party's governing body - was able to "overrule" concerns raised by the leadership.

The time has come,' old compo said,
      To talk of many things:
False News — and slips — and sealing-wax —
      Of cabbages — and things
And why my party is going to pot —
      And whether pigs have wings.'
