[Cut Off King]

According to YouGov:

Labour, Lib Dem and UKIP supporters oppose the sell-off by majorities of 78 per cent-11 per cent, 72 per cent-17 per cent and 76 per cent-18 per cent, respectively.
Conservative voters are less opposed, but still tend to oppose the plans by 48 per cent-40 per cent.
Additionally, while only 8 per cent of Conservative voters “strongly support” the sell-off, 20 per cent “strongly oppose” it;
among Labour, those who “strongly oppose” outnumber those who “stongly support” it by a ratio of almost 25 to 1.

Democracy is a lie

That's only if the persons polled are telling the truth.
And whether or not they can be bribed/persuaded to change their minds when the parliamentary vote (which I think is necessary to pass the sale) takes place.
