“This is appalling. The American XL Bully is a clear and lethal danger to our communities, particularly to children,” Ms Braverman wrote on social media.

“We can’t go on like this.

“I have commissioned urgent advice on banning them.”

The advice was commissioned last week, an adviser said, with it being the Department for Environment, Food and Rural Affairs’ responsibility to add the breed to the banned list.

Last week, two of the breed were shot dead for mauling 22 sheep in North Wales.

The owner of two dogs has been convicted following the livestock attack, which took place in Wrexham.

David Hughes, 26, admitted being in charge of a dog dangerously out of control and being the owner of a dog worrying livestock.

Mr Hughes was banned from keeping dogs for five years and ordered to pay £900 in fines.
