Although it has said it will not support Labour, the Sun has not explicitly endorsed the Conservatives, saying they have to do more to earn voters' trust....
The Sun's associate editor Trevor Kavanagh said the paper had been debating whether to withdraw its support from Labour for some time.
Although the paper's proprietor Rupert Murdoch had been "involved" in the decision, he said it was the paper's readers who had really driven the switch.
"They have turned off Gordon Brown and the Labour Party," he told the BBC's Daily Politics.
However, he said the Conservatives must say more about their policies on the economy, immigration and Europe.
"This is no blank cheque," he said. "We want them [the Tories] to put more flesh on the bones."
So yes, the Sun is following its readers.

Labour's deputy leader said her party was "angry" at the paper's decision to desert it, but urged members to use the move to inspire them to victory.
