No, he’s being quite clever, he’s not getting in the way of the Tories, but is allowing himself the opportunity to take a few Labour or LibDem seats, thereby holding Boris’s feet to the flames.....not sure it will work but he would have been pilloried if he’d helped Corbyn in any way......
His whole reason for being is Brexit.
He's now abandoned that ground to Johnson.
It's not clever in the slightest, unless you count him recognising he's been utterly destroyed and surrendering at the earliest opportunity as clever.
All he'll be hoping for now is that when Brexit is the obvious disaster it will be, then he can come back and try and claim its all because it wasn't REALLY Brexit.
