Simon Hughes, Lib-Dem MP for North Southwark and Bermondsey, who also attended the meeting, said: "We will be meeting with Home Office ministers to see what further action can be taken as soon as possible. The Met set up Operation Trident but it has not dealt with all the issues. We need police, immigration, politicians and Customs and Excise to unite in stopping this situation where young people are using firearms as a fashion accessory."
