In this section you'll find information about cookies – what they are, which ones we use on this site and how to manage them.Change cookie settings
Cookies are small files that allow a website to recognise and track users. The Information Commissioner's Office (ICO) groups them into three overlapping types:
These are files that allow a site to link the actions of a visitor during a single browser session. They are not stored long term and are considered "less privacy intrusive" than persistent cookies.
These remain on a user's device between sessions and allow one or several sites to remember details about the visitor. They may be used to target advertising or to avoid having to provide a password each visit.
First-party cookies are set by the site being visited. They are typically used to study how people navigate a site.
Third-party cookies are issued by a different server to that of the domain being visited. They could be used, for example, to trigger a banner advert based on the visitor's viewing habits.
Most web browsers automatically accept cookies, but you can usually change your browser setting to decline cookies if you prefer. The settings are usually accessed through the browser's Help function.
If you have any problems or need more details, you can visit www.aboutcookies.org for comprehensive information on cookies and how to change the settings on a wide variety of browsers, as well as how to delete cookies from your computer.
For information on how to do this on your mobile phone's browser, you'll need to refer to your handset manual.
