This is such a lazy trope. The vast majority of MPs (from all parties) are dedicated individuals working for their constituents - through work I've had dealings with several and have generally been impressed with their knowledge and capabilities. There are some scoundrels, chancers and idlers among them but, happily, they are few and far between.And Blair led us into an illegal war based on fabricated evidence. So he gets a plum assignment as a Peace Envoy.
No I didn't vote for Johnson, just pointing out that they are pretty much all corrupt and just after their own little power.
Johnson stands on his own as the most mendacious. indolent, two-faced and venal individual to have attained high office in my lifetime. I hope this is the end of his political career ... although I'm sure that his "what a character" schtick will pull in the dollars on the US circuit.
