Yvette Cooper as home secretary? She's a career politician with no actual work experience, certainly none relevant to her portfolio. Not to mention the fact that if you shone a torch in her ear you would see her eyes light up 
Ed Milliband in charge of achieving net zero by 2030? I'd laugh if it wasn't so bloody horrific. 
Cooper and Milliband have been very good these last years, excellent at holding the government to account in debates.
But we have a government that's given too many promises it can't keep, some daft ones it can and is only supported by 1 in 3 voters. Not just Uncle that'll end in tears.
