Newcastle-upon-Tyne was a parliamentary borough in the county of Northumberland of the House of Commons of England from 1283 to 1706, then of the House of Commons of Great Britain from 1707 to 1800 and of the House of Commons of the United Kingdom from 1801 to 1918. It returned two Members of Parliament (MPs), elected by the bloc vote system. Newcastle first sent Members to Parliament in 1283, although it was not always possible to act upon the writ of summons, which was disregarded on at least four occasions (1315, 1327, 1332 and 1337) because of warfare with the Scots.
