A TORY minister's Twitter account has changed its profile picture to an image of Elon Musk while promoting a fake cryptocurrency event.

Gillian Keegan's social media account was apparently hacked on Christmas evening when it started sharing links to a bogus event promoting a cryptocurrency once backed by the Twitter CEO.

The Education Secretary's profile appears to have been hacked at around 7.30pm on Christmas day but has continued to promote the "Tesla x Twitter First Event" through to Boxing Day.

While the Tory MP's cover photo shows her Chichester constituency work her profile picture remains an image of Musk, who took over as CEO of the platform in October.

Since Christmas, the account has replied to dozens of tweets about a fake event hosted by Musk's companies Twitter and Tesla.

The link, titled "Elon Musk - GET FREE DOGE, BTC & ETC", claims there will be a "special giveaway for all our fans and the crypto community".

Doge refers to Dogecoin, a cryptocurrency originally launched in 2013 as a joke that later saw its value sore by more than 18,000% following regular praise from Musk.

One tweet referred to people who own Dogecoin as "warriors fighting for the future".

Twitter's newly-added view count suggests the tweets have been seen by tens of thousands of people.

The UK Department for Education said it does not comment on hacks.
