Others include a man from Essex who runs a charity that helps to pay for veterans’ funerals, a woman from London who set up a charity to help adults deal with grief, and a woman from North Shields who built a play centre for disabled children.
“I can confirm that among the guests who have been invited to attend will be almost 200 people who were recognised in the queen’s birthday honours this year, that was in June," said the official spokesman for Prime Minister Liz Truss.
“These individuals drawn from across the UK were recognised for their extraordinary contributions in areas including the response to the Covid-19 pandemic, people who volunteered in their communities, charity workers and those who work in health care, education and the wider public sector.”
