Network Rail debt rises to £25.7bn

Network Rail's (NR) net debt has risen to £25.74 billion, the rail infrastructure company announced.

The figure - for the 12 months ending March 31 2011 - is an increase on the £25.05 billion figure for the previous 12 months. But NR, which has no shareholders and is a not-for-dividend company, said its net debt remained "at an expected level".
