Noticed a change?

The changes you have noticed to the site are part of a trial that we are currently running to test the potential benefits for our users of changing some elements of the site.

Users are selected at random for this trial, and the fact that you've noticed a change implies that you are one of those users. At no point will we personally identify you.

We hope that this isn't too inconvenient for you but if you wish to remove yourself from this trial then you can simply click here.

This type of testing is called multivariate testing (MVT).

MVT is an industry standard way of trying out changes to large websites and is used by many of the world's major online brands.

We use it on the BBC News website for no other purpose than to try and improve the experience of using the site.
