'The abuse started the day I met him'

Police in England and Wales received more than 900,000 calls about domestic abuse last year - an average of more than 100 calls an hour, according to a report by the police watchdog.
HM Inspectorate of Constabulary found the number of incidents recorded by police in the last 18 months has risen by almost a third. It says this is partly due to forces making domestic violence a priority since its last inspection, but it says there are still improvements to be made.
The news comes just two weeks before the government introduces "coercive control" as a new criminal offence, carrying a maximum prison sentence of up to five years.
