Great Britain's buoyant taekwondo squad are closing in on Olympic places for Rio next year after their latest impressive World Grand Prix performance in Turkey last week.

Olympic champion Jade Jones added another gold to her collection at -57kg while Bianca Walkden, crowned world champion earlier this year, was made to settle for silver.

Rachelle Booth was edged out in the semi-finals while men's trio Lutalo Muhammad, Damon Sansum and Mahama Cho all exited in the last eight in a team display that bodes well for the next Grand Prix in Manchester next month.

Jones in particular is relishing the opportunity of competing at home after winning both in Turkey and at the European Games in Baku in July despite admitting to feeling less than 100 per cent.

Jones said: "I'm always aiming to be the best in the world and if I can put in a good performance and win these events then it all helps for Rio.

"I'm driven to be better and better and I want another Olympic gold - but if I'm honest I haven't been feeling at my best.

"I'm really looking forward to Manchester now. To have friends, fans and family there will be great and it is very important for me and the GB team."

If Booth's emergence in the same weight category has kept Jones on her toes, Walkden also looks good for Rio after edging back into the top six qualifying berths.

Walkden won two consecutive golden point bouts before a controversial final loss to American Jackie Galloway, despite insisting an earlier score of her own should have won the match.

"I'm devastated because I thought my hook kick to the face had scored in sudden death," insisted Walkden. "But overall I did well and came through a tough competition and I am getting back on track."

Cho will also seek a boost in Manchester after falling in the quarter-finals of the heavyweight category to South Korea's eventual champion Cholho Jo.

Cho's qualification for Rio is currently hanging in the balance after a series of disappointing performances including a first stage exit in Baku.

But he insisted: "I've got to take the positives. People found it hard to score against me and I had a good day.

"We always say we'll go back to the gym and work on it, but that's exactly what I've got to do before the Manchester Grand Prix, because there's still a lot to aim for."

There was also encouragement in Turkey for Charlie Maddock, a surprise gold medallist in Baku and subsequent winner of the Israel Open, who despite losing her first round match pushed reigning world champion Ma Min-Ah of South Korea to a golden point.
