Dakota Johnson in a scene from 'Fifty Shades of Grey' : caning and spanking are banned under the new porn curbs in the UK

A mass protest against new porn laws is due to be held outside the British House of Parliament tomorrow.

Hundreds of activists are expected to simulate sex acts to campaign against a new law, which bans video-on-demand films from showing acts like spanking and caning.

The protest has been organised on Facebook by the Sex Worker of the Year 2013, Charlotte Rose, who believes that the new "measures appear to take aim at female pleasure".

The campaigners had hoped to break the world record for the number of people "face-sitting" at the same time, but the record has been rejected by Guinness World Records.

The acts will now be simulated. The organisers are hoping that the protest at Old Palace Yard does not coincide with a "weather bomb" of rain and wind that is due to hit Britain this week, but are bringing blankets, umbrellas and yoga mats in preparation.

The Board has strict policies on material which combines sexual detail with activity which is illegal, harmful, abusive, or involves a lack of consent or the infliction of pain or injury.

They are protesting against new rules introduced by the Audiovisual Media Services Regulations 2014 which mean that paid-for porn watched online will have to comply with the current British Board of Film Censors (BBFC) guidelines.

Liberal Democrat MP Julian Huppert is campaigning for the new rules to be reviewed, although so far only two other MPs have joined his movement. Porn bought and watched online will now have to comply with the BBFC R18 rating. (© Daily Telegraph, London)
