We have summarised the cookie types into the following three categories:

1. To provide you with the service you have asked for (Essential cookies). For example keeping you logged in during your visit. Without cookies the site might forget you and you’d have to constantly log back in. When you buy tickets, cookies make sure they’re still in your shopping basket when you get to the checkout.
2. To show adverts that are more relevant to your interests (Advertising cookies). For example we and third party organisations may use cookies to restrict the number of times you see the same advert or to show other adverts that may be more relevant to you – often called online behavioural advertising (OBA). OBA is a way of using information about your web-browsing activity, collected by using cookies, to group you with other users into interest groups and show you advertisements based on those interests.
3. To analyse and improve your browsing experience (Analytics & Customisation cookies). For example, for analysis purposes, we like to know what pages and links are popular and which ones don’t get used so much to help us keep our sites relevant and up to date. We also use them to customise your visits to the site, for example to remember choices you make such as your language or region.
