FXstreet.com (Córdoba) - Fitch Ratings affirmed UK long-term triple-A rating on Friday but kept a negative outlook and said that weaker than expected growth and fiscal outturns in 2012 have increased pressure on the UK's 'AAA' rating, which has been on negative outlook since March 2012.

"The Negative Outlook on the UK rating reflects the very limited fiscal space, at the 'AAA' level, to absorb further adverse economic shocks in light of the UK's elevated debt levels and uncertain growth outlook", Fitch said in a statement.
