But Mr Clegg said : 'It 's a measure of how much the Conservatives have run out of new ideas that the big idea on the day they publish their manifesto is a poor cover version of one of Margaret Thatcher 's 1980s hits . It does n't even add up , it 's not even affordable as the housing industry has said . ' 'It will not help people who do n't presently live in their own home , it does not help the youngsters who are living with mum and dad and want to move out , it does not help the millions of people in private rented accommodation who want to own their own home . 'As the housing industry has said , actually under this plan you will see affordable housing go down rather than go up . ' Miriam Clegg at a campaign event in Greater Manchester .
