Analysis

Stratford station isn't usually very busy at 0600 on a Saturday morning. But today it feels like the busiest - and friendliest - station on the planet.
The rest of London may be uncharacteristically quiet - as the capital recovers from a very late night of celebrations - but this place, at least, is still buzzing.
Cast members from Friday night's show are still hanging around the stadium steps, hugging and kissing - saying goodbye to new friends after months of secret rehearsals.
Many of them are carrying the drums and costumes they wore in the ceremony. One man staggered past me under the weight of a giant piece of artificial grass. Last night, it was part of the stadium's rural landscape. This morning it is the ultimate London 2012 souvenir.

"The roads in south-west London and Surrey will be exceptionally busy with a large number of temporary road closures for the cycling road races today and tomorrow."

He said public transport would also be "exceptionally busy" with people making their way to watch the cycling road race and to other venues.
But he said all transport "serving the spectacular opening ceremony ran well, getting everyone to the Olympic Park on time and home again".
Britain's other big medal hopeful of the day is Scotland's Hannah Miley, 22, in the women's 400m individual medley who is ranked third-fastest in the world this year in the event.
Team GB women's pair Heather Stanning and Helen Glover will be among the first to race as the Olympic rowing events begin in Berkshire.
In total, athletes will compete in 19 sports on Saturday with medals also due to be awarded in archery, fencing, judo, swimming and weightlifting.
Great Britain's swimmers skipped Friday night's ceremony because of their early start in swimming events at the Aquatics Centre.
On Saturday night, meanwhile, 14-time Olympic gold medallist Michael Phelps will race against rival and fellow-American Ryan Lochte in the 400m individual medley final.

Meanwhile, International Olympic Committee president Jacques Rogge - who sat next to the Queen at Friday night's opening ceremony - has praised the spectacular, saying it "bodes well for a successful Games".

"It demonstrated all that is good about British creativity," he added.
At the end of the ceremony, the Queen declared the London Olympics officially open, before seven young athletes were given the honour of lighting the ceremonial flame.
The seven, chosen by British Olympic champions, each lit a single tiny flame on the ground, igniting 205 petals, one for each competing nation or territory.
Long stems then rose towards each other to form a cauldron, signifying unity.
The flame had arrived via the Thames on a speedboat carrying David Beckham, who handed the torch to five-time rowing gold medallist Sir Steve Redgrave.
The show began with iconic images of London and Britain being beamed to the world, and all four countries of the UK being represented in song with a field at the stadium turned into a meadow with live animals.

The show moved through the "great revolutions in British society", from an agricultural setting through to the Industrial Revolution itself.
Steelworkers began forging material that transformed into golden Olympic rings prompting cheers from the 80,000-strong crowd.
There were cheers too as the crowd saw a film featuring a meeting between the Queen and Daniel Craig, as agent 007 James Bond.
"Good evening Mr Bond," she said before the pair left together, heading towards the Olympic Stadium in a helicopter.
The aircraft then flew over the stadium to the sound of the Bond theme tune, as two figures parachuted down, one dressed as the monarch, before the Queen appeared in the stands.
There were also appearances from comic actor Rowan Atkinson, as Mr Bean, as well as from musicians including Mike Oldfield, Dizzee Rascal and Sir Paul McCartney.
