Britain is no leader in nuclear security | Letters

You report David Cameron as asserting at the global nuclear security summit in Washington that, along with the US, "Britain is very much giving the lead on nuclear security on nuclear sites, transport and materials" (World leaders meet to plan for 'all too real' nuclear doomsday scenario, 2 April).

Unfortunately, the truth is the opposite; Mr Cameron and his ministers are deluding themselves if they believe this.
