DAY IN BRIEF:

Rebecca Adlingtonexternal-link produced a strong finish , but the double Olympic champion is still yet to climb to the top of the podium at a World Championships.

Scotland's Hannah Miley came sixth in the 200m individual medleyexternal-link (IM) in Rome two years ago, but was seventh in Shanghai.

However, Ellen Gandy impressed with a fifth-placed finish in the 100m butterfly, her first World Championship final.

Elsewhere, 15-year-old Ye Shiwen caused a sensation when the Chinese teenager beat more experienced opposition to the 200m individual medley title.

Whilst a tearful Cesar Cielo powered his way to gold in the 50m butterfly at the World Championships, a week after the Brazilian was cleared to compete having tested positive for doping in May.

Alexander Dale Oen paid tribute to the victims of the tragedy in Norway after he won the 100m breaststroke final.

The USA's Ryan Lochte beat Michael Phelps for the second time in a week and broke his own world record to claim gold in the 200m individual medley - GB's James Goddardexternal-link was close to tears after coming fourth.

Fran Halsallexternal-link was the fastest qualifier for Friday's 100m freestyle final after winning her semi-final in 53.48, whilst Britons Andrew Willis and Michael Jamieson qualified fifth and sixth fastest respectively for the Friday's 200m breaststroke final.

GB's 4 x 200m freestyle team won a bronze medal in Rome two years ago, but without the likes of Rebecca Adlingtonexternal-link and Jazz Carlinexternal-link, who compete in the 800m freestyle heats on Friday, this time around they finished sixth - although that did guarantee the team an automatic relay place at London 2012.

FRIDAY, July 29

DAY IN BRIEF:

Fran Halsallexternal-link missed out on a medal by just six-hundreths in the 100m freestyle final.

The Southport-born swimmer was the quickest qualifier, but her time of 53.72 seconds saw her come joint fourth, a result which she said 'hurt'.

American Ryan Lochteexternal-link won the 200m backstroke and helped the United States to the 4x200m freestyle relay title, his third and fourth gold medals in China.

SATURDAY, JULY 30

DAY IN BRIEF:

Baring a major surprise, Rebecca Adlington should return for the 800m freestyle final on the penultimate day of competition, an event in which she set the current world record of 8:14.10 at the Beijing Olympics.

Stephanie Proud produced an impressive performance to defeat both European gold and silver medallist Lizzie Simmonds and Gemma Spofforth at the British trials in March in the 200m backstroke. It will be interesting to see whether Florida-based Proud can make her mark on the international scene.

Great Britain's 2009 50m backstroke world champion Liam Tancockexternal-link will be looking to defend his crown in Shanghai, but it will not be straight forward with 2010's triple European champion Camille Lacourtexternal-link set to pose a considerable threat.

Fran Halsallexternal-link will also be expected to be in the mix for medals in the women's 50m freestyle final, but could this be the moment for Hannah Mileyexternal-link to throw down the gauntlet to her London 2012 rivals by claiming her first World Championship gold medal?

The Scottish swimmer finished an agonising fourth in the event two years ago and having claimed the European title over this distance in 2010 - is determined to add another medal to her collection.
