Old is not very trendy these days. Kenneth Clarke's candidature has sparked a considerable amount of debate because of his age, he is 65 years old.
This issue tells a lot about the depressing state of conservative politics in the UK. For those who weren't aware, Clarke has stood as a competitor for the post in the past 3 internal elections.
He is now a political mummy, who awakes from rest everytime internal elections are at stake. Thus, it is not his actual age that matters, but his political age: just beyond the limit.
