Military chiefs said today that they hoped to “allay people's fears” as they unveiled surface-to-air missiles which could be deployed at six sites across London during the Olympics.

This summer the Authors Cricket Club will attempt to marry the power of the written word with that goosebump moment that comes from the perfect cover drive

When we come to tally up the profit and loss account for the Olympics, there's going to be a lot in the debit column: bloated costs, Lord Coe's corporate toadying and the runaway creation of eyesores (I have to rinse with Optrex if I even catch a glimpse of bloody Wenlock and Mandeville).

Quality newspapers are normally quite boring. Not monumentally boring, just a bit dull and worthy. If they were a colour, they would be brown.

For the second Sunday in succession, Usain Bolt was a figure of isolation in Daegu Stadium. Seven days previously, in the immediate aftermath of his false start disqualification from the 100 metres final, he went pacing off into a quiet alcove at trackside, fuming at his own impetuosity, while the rest of the field chased down the track after the title he had won in world-record time in Berlin in 2009. Had Bolt not jumped the gun, in all probability his rivals would have been running for a silver lining.

The strains of "God Save the Queen" rang round Daegu Stadium yesterday. Sadly, it was not played in recognition of a second British gold at the World Championships; it was for the delayed presentation of the reward Dai Greene earned in the 400 metres hurdles on Thursday.

There was never much danger of lightning striking twice as Usain Bolt got back on his mark in the World Championship arena in Daegu yesterday.

Jamaican Usain Bolt was back to his best today, cruising into the world championships 200 metres final with the greatest of ease before whipping the crowd into a frenzy in Daegu.

Just as another golden hope turned into a silver lining for the Great Britain team in Daegu yesterday, the glint of a possible Midas touch came into view. It remains to be seen whether Dai Greene will succeed where Mo Farah and Jessica Ennis have failed and win gold at the World Championships in South Korea. In emerging from his 400m hurdles semi-final as a comfortable winner yesterday, though, the Swansea Harrier showed the assurance of a contender who is going into tomorrow's final in 24-carat condition.

They were talking about the twitch in Daegu yesterday but there was no sign of a knee-jerk reaction. The morning after Usain Bolt's disqualification from the World Championship 100m final, close scrutiny of the replay showed a momentary twitch in the "set" position by Yohan Blake immediately before Bolt blatantly false started.
