Despite the handguns ban imposed under the 1997 Firearms Amendment, research carried out following the implementation of the Act saw a 40 per cent increase in the number of gun crime incidents in the UK.
While the number of homicides from gun crime remained largely static for over a decade, 2007 proved a decisive year for this issue. A wave of gang related incidents were committed by teenagers against other teenagers, with some high profile cases ending in fatalities. London, Manchester and Nottingham were most notably affected.
In August 2007, these attacks culminated in the murder of an 11-year-old Liverpool schoolboy, Rhys Jones, hit whilst playing football outside his local pub. Following a lengthy police investigation and a trial lasting over two months, an 18 year old youth, Sean Mercer, a member of the 'Croxteth crew' gang, was convicted in December 2008 of the murder and sentenced to life imprisonment.
Other gang members were convicted of offences connected with the murder, including 21 year old James Yates, whose initial seven year sentence for providing the handgun used by Mercer was increased by the Court of Appeal to 12 years.
The then prime minister, Gordon Brown, came under constant pressure to resolve the issues driving these murders. Commentators highlighted a range of social problems which might be responsible including inner city poverty, family breakdown, and the absence of positive black role models in the UK.
The government also faced questions over the apparent availability of guns, which had remained strong despite the handgun ban. Some commentators also suggested the government's legislation, specifically punishments for carrying a gun, were exacerbating gun crime amongst the young.
Following the mass killings in Cumbria on 2nd June, 2010, Home Secretary Theresa May confirmed that two weapons had been recovered by police, a shotgun and a .22 rifle, and that the gunman, Derrick Bird, had held a shotgun licence since 1995 and a firearms licence (for the .22 rifle) since 2007.
Ms May pledged that when the police had completed their investigations, the Government would lead a debate on the country's gun laws, engaging with "all interested parties" and allowing MPs to contribute to the debate.
Concerns also continued to increase about the use of illegal firearms by street gangs and organised criminals.
In February 2012, the Home Secretary launched a consultation on strengthening the law in this area, in particular whether the penalty should be increased for illegal importation of firearms and also whether there was a need for a new offence of possession of illegal firearms with intent to supply.
The consultation was set to run for 12 weeks and sought the views of the public, the police, the CPS, victims groups, the judiciary, and voluntary organisations.
In its response to the consultation published in October 2012, the Government stated that it was clear there was strong support for taking a tougher stance on control of prohibited firearms.
It had been decided, therefore, to increase the maximum penalty for illegal importation of firearms to life imprisonment and to create a new offence of 'possession with intent to supply' . The changes would be implemented as soon as a legislative opportunity arose.
