Campaigners are stepping up their bid to have Cornish listed as a nationality in the 2011 census.
Thousands have joined the crusade online while MPs and councillors have pledged to lobby the Government to ensure people from Cornwall do not have their identity "swept aside just because they are small in number".

Critics say the omission will mean many people who consider themselves to be Cornish will not realise they can do this, and instead select one of the other options: English, Scottish, Welsh, Northern Irish or British.
In 2001, some 37,000 people recorded their nationality as Cornish, leading officials to assign the response a designated code for the first time…
