Some links come to us including GOV.UK or www.gov.uk at the end of the link text. Delete this 1) to avoid clutter and 2) because it is assumed our links should be to GOV.UK pages.
In the same way, if a link text ends with the name of any other website (NHS), (ONS), (WHO) remove these also.
In the same spirit don't write 'on the xxx website' - limit the link to the page title, or 'More information about x is available online'.
Do not write such and such 'is available on GOV.UK', so 'Further information about norovirus surveillance and rotavirus surveillance is available on GOV.UK' should be 'Find more information about norovirus surveillance and rotavirus surveillance'.
