"It was the second blow to Chatham's hopes after the docks lost out to the Forth Rail Bridge in Scotland for nomination in June 2012" I never heard any nomination on Forth Rail! Or did I miss something?
The English language used is a bit convoluted - It doesn't refer to an actual "nomination" - rather to the fact that Chatham "lost out" in Jun 2012 because the UK government decided then that the next 2 nominations should be for the Forth Bridge and Gorham's Cave. Chatham would had been hoping to be placed next in line as it was on the UK's previous T List and had already been postponed once a few years ago during the period when UK kept trying with Darwin at Downe. So now they have been put behind the Lake District too
See this report of the event dated 28 May 2012 which relates to Chatam's first "blow"! - https://www.gov.uk/government/news/two-new-uk-world-heritage-nominations-to-be-put-fo rward--2
By the way - since "Prepare a bid for 2014" means to deliver it in 2014 for consideration at the 2015 WHC after evaluation by ICOMOS during 2014, then, as I remember it, the deadline is 31 Jan 2014 - only a few days left!!!
All other countries hoping to submit Nomination Dossiers for consideration at the 2015 WHC should be dotting the final "i's" and crossing the final "t's" too!! We should soon be getting news from various parts of the World indicating whether the deadlines have been met or not
