BBC News just interviewed Ed Milliband, a MP who is acting as Shadow Secretary of State for Energy Security and Net Zero. IIUC, Shadow Secretaries act as counterparts to the govt secretaries and develop alternative policies and criticism. This means Labour will have a cabinet ready immediately.
BBC is also reporting that eight current Conservative cabinet ministers will not only lose their cabinet seats but have also lost their parliamentary seats. This seems like such a stunning repudiation of the Conservative Party. You really do love to see it.
