The football team Wolverhampton Wanderers have threatened craft ale giants BrewDog with possible legal action over their new logo.

The Scottish brewer, based in Ellon, Aberdeenshire, unveiled a black wolf's head design for its latest "Lone Wolf" spirits range.

It bares a resemblance to the football's club's emblem.

Now the Midlands club, which has patented various versions of the wolf's head both nationally and internationally, has contacted the firm demanding an explanation.

Wolves marketing boss Matt Grayson said: "This is a serious matter which has been independently raised by a large number of people.

"Some have even questioned whether Wolves has licensed its trademark to BrewDog.

"Therefore, it's causing confusion amongst our supporters and the general public and we'll be contacting BrewDog to seek more details and to bring our registered trademarks to their attention."

HeraldScotland:

BrewDog co-founder James Watt has said the "iconic" logo "manages to capture the craft essence of the brand in a clean, stealthy, understated way, which will make Lone Wolf instantly recognizable".
