Zaw Lin and Wai Phyo, launched the appeal after they were convicted of murdering Hannah Witheridge, 23, and David Miller, 24.

Zaw Lin and Wai Phyo were sentenced to death on Christmas Eve 2015 after being found guilty of the murders of Miss Witheridge, 23, and Mr Miller, 24, on the Thai island of Koh Tao in September 2014.

DNA evidence proved 'beyond reasonable doubt' the judges in the murder prosecution case ruled.

Zaw Lin and Wai Phyo, both from Myanmar, then appealed their death sentences.

It has been reported that a court in Koh Samui today upheld the death sentences given to the migrant workers.

The report said judges said evidence presented at the trial in December 2015 was adequate and reliable.

Miss Witheridge and Mr Miller, who was from Jersey, were beaten to death with a garden hoe and their bodies left for dead on a beach on the island.

Miss Witheridge, a former University of East Anglia and Langley School student, had also been raped.
