They passionately believe the British police should be involved in investigating Tyrell's murder.
I don't come to the chamber this evening to assert any individual's guilt or innocence.
But I would like to say for the record that Myles Litchmore-Dunbar maintains his innocence and argues on the night of July 23 in Malia he was also attempting to break-up a brawl, which led to the stabbing of Tyrell.
On the basis of what I have been told I believe there is reason for the British Government to be worried that the process under way in Greece at the moment will not result in the sort of justice that we would expect to be delivered in our own country.
I want justice to be done. I want the right person to be convicted for the murder of Tyrell Matthews-Burton and I want the British Government to help make this happen.
