If you are viewing our website using Google Chrome browser on a desktop computer, you may be having problems opening some files at the moment. This appears to have been caused by a recent update to Google Chrome, which Google are investigating.
If you are unable to open a file in Google Chrome (are just getting a grey screen), please right click on the file link and select ‘save …. as' to download a copy of the file, which you will then be able to open.
Other browsers such as Internet Explorer or Microsoft Edge are unaffected.
