In his Sky News interview Tobias Ellwood, the Conservative chair of the Commons defence committee, said the security and defence review said that the UK could use nuclear weapons to respond to an attack with chemical or biological weapons. That was a “big change” in policy, he said.

He was referring to this passage on page 77 of the document (pdf).

The UK will not use, or threaten to use, nuclear weapons against any non-nuclear weapon state party to the Treaty on the Non-Proliferation of Nuclear Weapons 1968 (NPT). This assurance does not apply to any state in material breach of those non-proliferation obligations. However, we reserve the right to review this assurance if the future threat of weapons of mass destruction, such as chemical and biological capabilities, or emerging technologies that could have a comparable impact, makes it necessary.
