Knife crime reached a record level last year in England and Wales, while there was the highest number of homicides for more than a decade, official figures show.
These figures show an increase of 6% in a year and the largest total since comparable data began in 2011.
The number of homicides last year stood at 732, the highest in any calendar year since 2007 when it hit 765.
The data released on Thursday by the Office for National Statistics (ONS) came after a spate of knife crimes involving young people triggered a political row over cuts to police funding.
Fellow West Yorkshire Labour MP Yvette Cooper, who chairs the Home Affairs Select Committee, said the "disturbing increase" in violent crime comes as arrests continue to fall.
Homicides, which include murder and manslaughter, increased 6% in the 12 months leading up to December compared with the year before.
The ONS release showed an increase in knife offences in 31 of the 43 police forces across the two nations.
The Metropolitan Police recorded the largest volume, at 14,660, but this was an increase of just 1% in a year.
Merseyside was up 35% and North Yorkshire 21%, while British Transport Police saw an increase of 54%.
The number of violent offences recorded by police was more than 1,608,500 last year - a 19% increase on 2017.
However, the Crime Survey for England and Wales (CSEW) suggested there was no overall increase in violent offences.
The ONS considers the CSEW a better indication of overall trends for this type of offending because lower-level attacks may be picked up in the survey but not reported to officers.
The total number of crimes recorded by police was 5.8 million, which was 7% more than in 2017.
