A team of experts from across the government have been brought in to form a new unit to "look at the potential extent, scope and impact of disinformation which is being spread on social media platforms," said the DCMS in a statement.
As part of this, the unit will hold discussions with social media companies over how they monitor interference and limit the spread of disinformation.
Announcing the unit, the DCMS said officials would be "working with strategic experts" to ensure the government is prepared to respond.

On Sunday, Britain reported its third coronavirus-related death.
