Crimes using knife have more than doubled in many parts of the UK since the beginning of austerity led by conservatives, revealed new figures.

Police forces in England and Wales have seen an increase in stabbing violence, some increasing by 135%.

This follows Mirror Online's release of exclusive figures showing how hundreds of young worker jobs have been lost across the country, and dozens of jobs have also been cut.

Activists say that there is no doubt that cuts in youth services have resulted in an increase in the number of crimes committed with a knife, and a council official said the youths had paid with their lives.

The shocking statistics of the government show that in the 12 months leading up to March this year, there were 47,100 crimes involving a cutting weapon in England and Wales.

In 2015/16, they were less than 30,000 and in 2010/11, just under 31,000.

The most recent figures for knife crimes include 285 homicides.

Merseyside is one of the regions that has experienced a sharp rise in knife crime

This follows more than a decade of dark cuts in public services as the number of police officers has been reduced to nil.

In 2010, Home Office figures revealed that there were 140,000 police in the UK.

But after the government introduced its austerity program, it has declined sharply.

Eight years later, there were 117,000, a decrease of 23,000 – more than the 20,000 officers Boris Johnson had pledged to recruit when he became prime minister.

The government has denied that the cuts have resulted in an increase in serious violent crime.

However, last April, a leaked Home Office report revealed that the decline in the number of police officers "may have encouraged" violent offenders, which "probably contributed" to an increase in violent crime.

In Merseyside, crimes involving blades and sharps have increased by 135% since 2010, according to figures from the Office for National Statistics.

And in the Northeast, the number of reported incidents has increased by 102%, with Northumberland recording an increase of 135%.

The alarming numbers also show a 90% increase in the southeast, while Dyfed-Powys in Wales has recorded a rise of 133%.

The total number of crimes committed with a knife has increased by 38% in England and Wales since the beginning of the decade.

In a video speech earlier this year, Jeremy Corbyn, leader of the Labor Party, said the youth were paying for life for austerity, and described the knife crime as a "national emergency."

He said, "I sat in the living room of too many families in my own community to console them after the loss of a child.

"Hundreds of young people have lost their lives. This is a national crisis and the situation only worsens.

"Since 2010, 21,000 policemen have been removed from our streets and 760 youth centers have been closed.

"We have witnessed the tearing of the social fabric of our communities."

Boris Johnson has unveiled controversial new plans for arrest and search and has pledged to recruit 20,000 police to replace the lost.
