Quote of the day - All politicians flip-flop from time to time; but Mr Romney could win an Olympic medal in it.

WHEN Mitt Romney was governor of liberal Massachusetts, he supported abortion, gun control, tackling climate change and a requirement that everyone should buy health insurance, backed up with generous subsidies for those who could not afford it. Now, as he prepares to fly to Tampa to accept the Republican Party’s nomination for president on August 30th, he opposes all those things. A year ago he favoured keeping income taxes at their current levels; now he wants to slash them for everybody, with the rate falling from 35% to 28% for the richest Americans.
