"The British government says that for Sinn Fein to be involved in talks the guns must be left at the door"

This quote by Martin McGuinness is describing the British government's position on the involvement of Sinn Fein in peace talks. The British federal government is making it clear that in order for Sinn Fein to be associated with the talks, they need to leave their weapons at the door. This is a clear indication that the British government is not going to work out with Sinn Fein unless they are willing to give up their weapons and devote to a serene resolution. This is a difficult choice for Sinn Fein, as they have utilized their weapons to eliminate for their cause in the past. However, if they want to make this sacrifice, it could be a major step forward in the peace process. Eventually, it depends on Sinn Fein to choose whether they are willing to leave their weapons at the door and take part in the peace talks.
