Dopers will lose right to represent Britain, says UKA boss Warner

British athletes banned for doping were formerly banned for life from representing GB at the Olympics

British athletes will be asked to sign an agreement that will ban them from competing for GB if they are found guilty of a serious doping offence.

"If you want to be selected, one of the things you have to do is sign," said UK Athletics boss Ed Warner.

He wants the agreement in place for the 2016 World Indoor Championships, taking place in Portland, Oregon in March.

He told British MPs such an agreement "has never been tested" in court but said UKA was talking to its lawyers.

Warner also called for Russia to be prevented from sending an athletics team to the 2016 Olympics in Rio de Janeiro.

The country was banned from international athletics competition following an independent World Anti-Doping Agency report that alleged widespread doping by Russian athletes.

Warner believes the "state-organised" scandal has been so serious that Russia should not be allowed to send athletes to Brazil.

Former British world champion sprinter John Regis told BBC Radio 5 live: "I would have found it very easy to sign for the simple reason that I know that I'm a clean athlete. I would have just read it, said yeah that makes a lot of sense a put my signature down the bottom."

Doha World bids under scrutiny

According to Warner, speaking at a Culture, Media and Sport select committee on Tuesday, Doha's bids for the 2017 and 2019 World Championships have been referred to the IAAF ethics commission.

However, he refused to reveal the names of the IAAF figures who had told him of rumours of brown envelopes full of cash being handed out just before the vote for the 2017 World Championships, which London won.

Warner said: "I have had a number of discussions with the IAAF and they have told me the 2017 and 2019 bids by Doha have been referred to their ethics commission."

Asked if IAAF president Lord Coe was one of those who had told him of the rumours, Warner replied: "It could have been any number of people."

Coe was a senior member of London's bid team before succeeding Lamine Diack as IAAF president in August last year.

Leaked emails from Diack's son, Papa Massata Diack, have revealed he appeared to request $5m from Doha while it was bidding against London.

Papa Massata Diack is wanted on corruption charges by Interpol,

French prosecutors are also looking into the awarding of all world championships from 2009 to 2022 as part of their IAAF corruption inquiry.

The Qatari athletics federation has always denied any wrongdoing.
