Brexit could hurt UK’s credit score, says ratings agency

Fitch, which rates Britain just below top AAA level, warned leaving EU would be 'moderately credit negative'

A vote to leave the EU in the forthcoming referendum could hurt the UK's strong credit score, the ratings agency Fitch has warned.

Fitch, which cut its rating on the UK to a notch below the top AAA level in 2013, said on Monday a vote for Brexit would be "moderately credit negative" for the UK, putting at risk its medium-term growth and investment prospects, its external position, and the future of Scotland within it.
