A cookie is a simple text file that is stored on your computer or mobile device that allows us to 'remember' you either for the duration of your visit (a temporary or session cookie) or for repeat visits (a permanent or persistent cookie).
The cookies we use allow us to identify whether or not all of the pages which you request are successfully received and allow us to aggregate usage statistics about the site. This information enables us to recognise popular site features and further develop new ones, adding to the overall visitor experience of the site. For this we use a programme called Google Analytics, which is purely statistical data generating and cannot be used to find out the identity of a user. These cookies are anonymous and allow us to improve our websites.
