MPs will decide this week whether to grant themselves anonymity if they are arrested.
Making their names public could breach their right to privacy under the European Convention on Human Rights, they say.
Under the current rules, the House of Commons must be notified any time a member is arrested by police. The details are then printed in the official parliamentary record so the public can know about any criminal proceedings involving elected members.
But a review by the powerful Procedure Committee, which oversees the rules governing the Commons, has called for MPs’ names to be kept secret to protect their ‘right to privacy’ under the European Convention.
The recommendation has been endorsed by ministers and has been scheduled for debate on Wednesday but could be nodded through without a vote.
