Police in Thailand say they could be closing in on a breakthrough in the murders of British tourists David Miller and Hannah Witheridge.
Officers are awaiting the results of DNA tests on their chief suspects - six Burmese migrant workers.
And as ITV News correspondent Neil Connery reports, two British men have also been tested, who police say need to be ruled out:
The Foreign Office is "aware" Thai police have spoken to British nationals in connection with the murder of two British backpackers in the country, a spokeswoman said:
We are aware of reports that the Thai police have spoken to British nationals in connection with the case. The investigation is a matter for the Thai authorities. We stand ready to provide consular assistance if required.

Deputy National Police Chief Somyot Poompanmoung told ITV News the results could take "a couple of days".
"Once (the results) are in we will know if they can be ruled out of the investigation and if they can be free to go," he said.

Two British men were stopped by police as they attempted to fly back to the UK by Thai police investigating the murders of two British backpackers in Koh Tao, according to reports in Thailand.
The two men, who are reportedly brothers, were said to have been stopped at Suvarnabhumi International airport last night before boarding a London-bound flight.
Thailand’s Deputy Police Chief General Somyot Pumpunmuang was quoted by the Nation newspaper in Bangkok saying that the men were being asked to stay for 48 hours.
A British man questioned in relation to the murders of two Britons found dead in Thailand has undergone a physical examination including a DNA test, a Thai police spokesman said.

Thai Prime Minister and junta chief General Prayuth Chan-Ocha appeared to question the behaviour of two Britons leading up to their murder on the island of Koh Tao.
Apparently referring to Britons David Miller and Hannah Witheridge, he is quoted as telling reporters:
We have to look into the behaviour of the other party too because this kind of incident should not happen to anybody and it has affected our image.
General Prayuth reportedly added that Thai authorities must tell “tourists when the safe times are to be outside. We have to help them understand.”
Thai police investigating the deaths of Britons David Miller and Hannah Witheridge have released six Burmese nationals without charge after questioning, according to the Bangkok Post.
The newspaper reports that the six men were colleagues but appear not to have been together on the night of the murders. Three of them were reportedly seen drinking near the crime scene.
An unnamed police source is cited as saying that one of the Burmese nationals looked similar to the "prime suspect" seen running in CCTV footage.
The families of the two British tourists, murdered in Thailand, spoke of their shock and their loss today, as police on the island of Koh Tao released CCTV pictures of one of their main suspects.
