No, I don't think so. Not in the way the geriatric of the US political establishment are.

These are the experienced backbenchers who've been around since Thatcher's days, but none of them are 85 year old corrupt cronies. Being an MP in the UK is absolutely nothing like being a US senator. It's quite unglamorous in most respects, doesn't pay all that well, and requires a lot of constituency work.

To be around that long you really have to be an excellent constituency MP, which correlates with at least being a decent person, someone of substance who actually cares about the constituents. The Labour party had such people too - Frank Field (now no longer with us), Kate Hoey, etc. Not party-line robots, and certainly not there to graft the system. Actual decent human beings.
