Geneva Conventions and United Nations Personnel (Protocols) Bill [Lords]

I am grateful to the Minister, who is being extremely generous in giving way. However, I return to the point made by my hon. Friend the Member for Buckingham (John Bercow). If she cannot answer now, perhaps she will be able to answer at the end of the debate. As I understand it, the red crystal symbol has been in force internationally since 14 January 2007. Why has the Bill taken so long to get here? Why does its commencement provision not use the word ““forthwith””?
