"This beautiful memorial has been in place for many years and we are very mindful of our duty to protect and preserve it. Our Healthy Spaces team is hard at work organising repairs."

He said: "Members of the the Walsall branch of the Mercian Volunteers Regimental Association are saddened to hear about this wanton vandalism.
"We are more determined to go ahead with the annual act of Remembrance on Friday, November 6 at 11am with social distancing."
