Politicians?

I have some Irish friends staying at the moment, which means the tea consumption has gone through the roof, along with the cake, potato and cream.

I parked briefly behind a car to undertake a small commission, and when I returned my friend said:
" Do you think that's directed at all politicians?"
He was referring to the number plate which started L I B 1234.
Underneath, in the small space where usually there is an advert for the car selling company, the owner had had printed
" Lazy Ignorant Bastards, the lot of them!"
