Design and accessibility

This website has been designed for a screen resolution of 800x600 and for Internet Explorer and Netscape compatible browsers of version 4.0 and above. Please be aware that if you are using a browser which differs from this specification, or Netscape 6.0, you may experience difficulties viewing this site. These can often be resolved by visiting your browser website and downloading an upgrade:

If accessing the site using a screen resolution of below 800x600, the pages will be legible but some horizontal scrolling may occur.

Alternative ways to view Adobe Acrobat documents

This site uses Adobe Acrobat to display certain documents. If your screen reader software (for example an audio-enabled web browser) is not compatible with the free Adobe Acrobat Reader, an online tool is available which converts the content of PDF files to a format which can be understood by most screen reader applications.

The URL of the document can be submitted via email or web form; the content is then converted either to HTML (standard web page format) or to plain text. For more information and full details of how to use this tool, please visit
