The "establishment" doesn't automatically equal right wing... the establishment will always exist in some shape or form, regardless of the political ideal of the government of the day.
As MikeFrog says, the establishment in the UK has a general left wig leaning.
As a country, I think our overall pilotics is rather more left-of-centre on a global spectrum... Consider the US, where Obama's party is considered left wing there, but is probably on a par to the UK Tory party in terms of actual policy.
