A radical transgender activist organization is reportedly planning a series of assaults on the offices of prominent politicians, including that of the Prime Minister, as uncovered by The Mail on Sunday.

The militant faction known as Bash Back has also announced intentions to target Wes Streeting, following an incident earlier this year where his constituency office was vandalized.

The activists declared, “If you think we’re finished, think again.”

They added, “Whether it’s an MP or the PM, you’ve encountered us once, and you’ll encounter us again.”

This newspaper discovered the group’s plot as they encouraged members to create ‘cells’ aimed at orchestrating acts of criminal damage against prominent figures.

Other potential targets reportedly include the Free Speech Union (FSU) and the feminist group Sex Matters.

Last night, we notified the Metropolitan Police and the parliamentary security services of our findings.

FSU founder Lord Young commissioned an independent security briefing about the group, which is calling for ‘total transgender liberation’.

The report, obtained by The Mail on Sunday, suggests British intelligence is monitoring the trans activist cells.

In a pamphlet obtained by this newspaper, Bash Back claims to target ‘organisations that promote transphobic rhetoric – from banning hormones and puberty blockers, to confining us to or defining us out of categories of woman and man, to promoting conversion therapy and facilitating hideous harassment campaigns’.

It says they ‘should come to expect us’, adding: ‘All of our targets have blood on their hands. We refuse to let them wash it off in peace.’ 

Bash Back’s first public attack was on Mr Streeting’s Ilford North constituency office in July, when it painted ‘child killer’ and smashed windows months after puberty blockers were banned for children on the advice of medical experts and the Cass Review of gender identity services.

Since then, the group has formulated an action guide – seen by this newspaper – for sympathisers to carry out similar attacks.

The document details how to avoid police detection as they plot criminal damage and steal equipment while filming their actions.

A security briefing on the group – also seen by The Mail on Sunday – reveals it has gone to extensive lengths to hide its identity, including removing internal metadata from public documents and using ultra-secure email systems.

The security memo says: ‘Given the first attack was on the office of a HM Gov minister, almost certainly the group responsible will be investigated by security services.’

Activists engaged in criminal activity could be among the near 3,000 profiles following Bash Back across social media platforms, the security document adds.

Maya Forstater, the chief executive of Sex Matters – also included in the list of offices that are potential targets – said: ‘After years in which police forces rolled out the red carpet for trans lobby groups and harassed women’s rights campaigners, it’s no wonder that Bash Back seems to believe it can cause criminal damage with impunity.’

A government spokesman said: ‘Threats, harassment, and vandalism are not only cowardly, they’re criminal and we will pursue anyone who targets politicians and their staff in this way, with the full force of the law.

‘The rhetoric from this group is dangerous and only seeks to distract from our work to improve the lives of trans people.’
