The Childline phone service recorded an increase of 20,000 calls last year, according to its annual statistics.

There were more than 837,000 contacts with the service in 2010.

Only 65% of calls were answered due to limited resources and Childline says that situation cannot be improved without increased resources and improved technology.

There are 500 volunteers at eight centres across the country who listen to and provide support to children and teenagers every day.

Over 2,000 calls are received every day.

The service is run totally on the basis of donations and sponsorship.

Childline, a free phone service available 365 days a year for people up to the age of 18, is available on 1800 666666.

The ISPCC has launched its summer campaign following the release of the Childline statistics called 'I can’t wait until I grow up'.
