This sign has been removed from the House of Commons for the most important of reasons

A sign which hung in one of the House of Common's tax payer subsidized bars has been taken down for an important reason.

Lewis Basset, believed to be a parliamentary aide, shared an image of a sign which purportedly hung in one of the bars of the House of Commons.

The sign allegedly appeared in the Sports and Social Club, which The Sun reported as being known as 'the man cave'.

In words given a greater and more chilling significance by recent revelations of a culture of secrecy around sexual assault in Parliament, the sign read:

What happens here stays here! Violators will be shot - survivors will be shot again

On Monday, when the sign was still hanging, The Sun also reported it had been graffitied in pen with the words 'It's sexist - it's 2017'.

The photos shared by Bassett show it being peeled off the wall, to which it had been attached with Blu Tack.

The fact that the 'man cave' attitude of the Commons has been brought under greater public scrutiny may explain why the sign has been taken down.

There is a Lewis Bassett-Yerrell listed as a member of staff to Labour MP Chris Williamson in the House of Commons register.

The sign in question appears to be a product of My Word, a 'family' sign making company based in Massachusetts, USA.
