I wouldn’t ask about chalk bags when there is so much damage much of the metalwork will have to stay in place.

I would start by asking to whom I should write about the original budget to ask how it was calculated and what it was supposed to cover and I would copy it to my MP and Lord Avebury.

Hi tpaifc
Why not start at the top and drop put in a request under the freedom of information act to the Secretary of State for Culture, Media and Sport or drop EH's Chief Executive, Dr. Simon Thurley a line.
You can find a list of all of the EH directors on their website.
Take a leaf out of Junes book, positive action instead of sniping.

cheers
