Clwyd South MP Susan Elan Jones has spoken in support of keeping the existing Hunting Act unchanged.
MPs will be voting on whether to amend the Act this Wednesday.
"All of us who come from the countryside know full well that the population of foxes has to be controlled. But most of us also think that a so-called 'sport' where foxes are chased and ripped up by hounds is cruel and does not belong in the 21st century.
"I'd like to see a huge majority of MPs, including those Plaid and Tory MPs who have previously been pro-fox hunting, vote against changing the Hunting Act on Wednesday."
