Emergency calls to the police can account for up to 20% of all calls in some areas while across the country the average is 10%, a Freedom of Information request has revealed.
However experts believe the vast majority of incidents go unreported.
The Guardian report:
The figures, obtained by the Labour party, reveal that Merseyside police had the highest proportion of domestic incidents in emergency calls received between April 2010 and April 2012, 43,995 out of 207,326 (21.2%). West Mercia police had the second highest with 18,041 of 99,188 emergency calls concerning domestic violence. Wiltshire had the lowest with 4,073 of 56,363 (7.2%).
