of Welsh speakers declined in Gwynedd from 72.1% in 1991 to 68.7%, and in Ceredigion from 59.1% in 1991 to 51.8%. Ceredigion in particular experienced the greatest fluctuation with a 19.5% influx of new residents since 1991, partially attributable to the inclusion of transient college students at local universities. The census also revealed that one-third of the population of Wales described themselves as of British nationality, with respondents having to write in whether or not they were Welsh. Controversy surrounding the method of determining nationality began as early as 2000, when it was revealed that respondents in Scotland and Northern Ireland would be able to tick a box describing themselves as Scottish or Irish, an option not available for Welsh respondents. Prior to the Census, Plaid Cymru backed a petition calling for the inclusion of a Welsh tickbox and for the National Assembly to have primary law-making powers and its own National Statistics Office. With an absence of a Welsh tickbox, the only other tickbox available was 'white-British,' 'Irish', or 'other'. Critics expected a higher proportion of respondents describing themselves as of Welsh nationality had a Welsh tickbox been available. Additional criticism targeted the timing of the census, which was taken in the middle of the Foot and Mouth crisis of 2001, a fact organisers said did not impact the results. However, the Foot and Mouth crisis did delay UK General Elections, the first time since the Second World War any event postponed an election. The Mittal Affair Controversy ensued in 2002 as Adam Price exposed the link between UK prime minister Tony Blair and steel magnate Lakshmi Mittal in the Mittal Affair, also known as 'Garbagegate' or Cash for Influence. Mittal's LNM steel company, registered in the Dutch Antilles and maintaining less than 1% of its 100,000 plus workforce in the UK, sought Blair's aid in its bid to purchase Romania's state steel industry. The letter from Blair to the Romanian government, a copy of which Price was able to obtain, hinted that the privatisation of the firm and sale to Mittal might help smooth the way for Romania's entry into the European Union. The letter had a passage in it removed just prior to Blair's signing of it, describing Mittal as "a friend". In exchange for Blair's support Mittal, already a Labour contributor, donated £125,000 more to Labour party funds a week after the 2001 UK General Elections,
