They can become TV pundits, radio personalities, retire (again), go into UK politics or simply go back to normal life.
Some of them didn’t get their £7.5k a month for very long and knew it probably wasn’t for the long haul So if they got a mortgage or loan on the back of it, more fool them lol
Although if that £7.5k a month was mine (expenses being another matter) I wouldn’t need to work for a while as that’s more I would have earned and could have saved quite a bit. ;-)
