Deputy Marc Leadbeater says perceived attacks on his reputation would be a distraction to the cannabis requete.
Deputy Marc Leadbeater, who heads up Home Affairs, writes in an email to all deputies that he believes he and his committee have been under 'a sustained and escalating campaign of unfounded allegations.'
These, it is understood, relate to his former shareholding in a local medicinal cannabis company.
The States' website, parliament.gg, shows there are currently no Code of Conduct investigations against him.
He says in his email that 'there is a very real risk that Wednesday’s debate would be overshadowed and undermined.'
Given this, he has decided to withdraw it from Wednesday's States agenda (25 March).
'This decision has not been taken lightly. It follows careful consideration and discussion with my fellow Requérants and other senior States Members.'
He does intend to bring the Requete again, which asks for committee representatives, led by Home Affairs, to examine the impact of a regulated cannabis industry in Guernsey.
