Trail hunting must be ended on public land over concerns the practice is being used as a cover for illegal fox hunting, ministers have been told.
Both Labour and the League Against Cruel Sports criticised the government for granting licences ahead of Boxing Day meets.
National Trust members have voted to halt the sport on the charity’s land over concerns it was being used as a cover, a move echoed by Natural Resources Wales.
But activists expect more than 240 hunting days will have taken place on land owned by the Ministry of Defence this year.
Labour’s shadow environment secretary Jim McMahon said: “Allowing hunts to go ahead on public and Government-owned land is completely irresponsible, regardless of whether those taking part are the Prime Minister’s mates.
“The Government must do more to close the loopholes that allow people to break the law and consign hunting to the history books, where the vast majority of us believe it belongs.”
Chris Luffingham, the director of external affairs at the League Against Cruel Sports, added: “It’s time all major landowners permanently banned trail hunting on their land and that the Government strengthens the Hunting Act to ensure its loopholes can no longer be exploited.”
In October, director of the Masters of Foxhounds Association Mark Hankinson was found guilty of intentionally encouraging huntsmen to use legal trail hunting as “a sham and a fiction” for the unlawful chasing and killing of animals during webinars.
National Trust members overwhelmingly voted to ban trail hunting on the charity’s land in England and Wales after the conviction at Westminster Magistrates’ Court.
The Welsh Government nature agency Natural Resources Wales, which looks after swathes of countryside and forests, also went on to ban trail hunting on its land.
The Hunting Act 2004 banned hunting wild mammals with dogs in England and Wales.
With hunts not traditionally meeting on Sundays, Boxing Day meets will instead be held this year on Monday.
