More than 100 official UK Government email addresses are at the centre of a major leak of hacked data from the Ashley Madison adultery website.

Personal details of up to 32 million users of the site, which has the tagline "Life is short. Have an affair", were released after it was hacked last month by a group calling itself The Impact Team.

Hackers are now said to have fulfilled their threat and dumped 9.7 gigabytes of data - including card, account details and log-ins - on the Dark Web, which is only accessible by a covert internet browser.

Among the email addresses are many work accounts, including thousands of those used by government workers - more than 100 of them said to belong to UK Government workers.

However, it is unclear if members provided legitimate details as it is possible to create an Ashley Madison account using someone else's name and email.
