Some information is held by the House of Commons. Whilst there is no official log for recording incidences of animals being brought onto the Parliamentary Estate without permission, a partial record of relevant incidences is held by the House of Commons.
Please note that our response below only deals with information relating to the House of Commons and Members of Parliament. The House of Lords is a separate public authority for the purposes of the Freedom of Information Act, and they may hold information about Peers in relation to your request, so you may wish to consider forwarding your request for information to them at FOILORDS@parliament.uk.
Please also note, that where an animal is reported on the estate, the Member is reminded of the rules in place. The current Administration Committee rules prohibit animals being brought onto or kept on the Estate, or any of its outbuildings (other than residences), except for certain specified exemptions. This rule is in place because of the duty of care that would arise in relation to animal welfare and the health, safety and wellbeing of Members, staff and visitors on the Parliamentary Estate.
There have been no recorded incidents, as detailed above, from 1 January 2017 to the date of your request.
Please note, the names of the individual MPs have been withheld. The information is exempt by virtue of section 40 (2) of the Freedom of Information Act 2000 (the exemption for personal information), as disclosure of this information to the public generally, in the House’s view, would not be consistent with data protection principles in the Data Protection Act 1998 (DPA). This is an absolute exemption and the public interest test does not apply.
