 "The Sun" printed a series of articles by disillusioned former Labour ministers (Reginald Prentice, Richard Marsh, Lord George-Brown, Alfred Robens and Lord Chalfont) detailing why they had switched their support to Thatcher.She explicitly asked Labour voters for their support when she launched her campaign in Cardiff, claiming that Labour was now extreme.Choosing to start her campaign in the strongly Labour-supporting city was part of Thatcher's strategy of appealing to skilled manual workers (NRS social group C2), whom both parties had previously seen as certain Labour voters; she thought that many of these would support her promises to reduce unions' power and enact the right to buy their homes.
