A Treasury spokesman said today's Fitch downgrade was a sign that Britain must continue to reduce its debt:
This is a stark reminder that the UK cannot simply run away from its problems, or refuse to deal with a legacy of debt built up over a decade.
Though it is taking time, we are fixing this country's economic problems.
The deficit is down by a third, a million and a quarter new private sector jobs have been created and the credibility we have earned means households and businesses are benefiting from near record-low interest rates.
