Irish similar to those in the Republic. Approximately 14% of the population speak Irish, however only 1% speak it as their main language at home. Under the St Andrews Agreement, the British government committed itself to introducing an Irish Language Act, and it was hoped that a consultation period ending on 2 March 2007 could see Irish becoming an official language, having equal validity with English, recognised as an indigenous language, or aspire to become an official language in the future. However, with the restoration of the Northern Ireland Assembly in May 2007, responsibility for this was passed to the Assembly, and the commitment was promptly broken. In October 2007, the then Minister of Culture, Arts and Leisure, Edwin Poots MLA, announced to the assembly that no Irish Language Act would be brought forward. As of April 2016, no Irish Language Act applying to Northern Ireland has been passed, and none is currently planned. Some resent Scottish Gaelic being promoted in the Lowlands. Gaelic place names are relatively rare in the extreme south-east (that part of Scotland which had previously been under Northumbrian rule) and the extreme north-east (part of Caithness, where Norse was previously spoken). Two areas with mostly Norse-derived placenames (and some Pictish), the Northern Isles (Shetland and Orkney) were ceded to Scotland in lieu of an unpaid dowry in 1472, and never spoke Gaelic; its traditional vernacular Norn, a derivative of Old Norse mutually intelligible with Icelandic and Faroese, died out in the 18th century after large-scale immigration by Lowland Scots speakers. To this day, many Shetlanders and Orcadians maintain a separate identity, albeit through the Shetland and Orcadian dialects of Lowland Scots, rather than their former tongue. Norn was also spoken at one point in Caithness, apparently dying out much earlier than Shetland and Orkney. However, the Norse speaking population were entirely assimilated by the Gaelic speaking population in the Western Isles; to what degree this happened in Caithness is a matter of controversy, although Gaelic was spoken in parts of the county until the 20th century. Non-recognition Scots within Scotland and the regional varieties of English within England receive little or no official recognition. The dialects of northern England share some features with Scots that those of southern England do not. The regional dialects of England were once extremely varied, as is recorded in Joseph Wright's English Dialect Dictionary and the Survey of English Dialects,
