The 28-year-old biology teacher was joined in the final stages of the walk on Monday by Gavin Strang MP.

In June, Gordon Brown and Nicolas Sarkozy published a joint statement, in an open letter to Burma's democracy leader, Aung San Suu Kyi: "We wish to use this opportunity, on the occasion of your birthday, to reaffirm our commitment to your lifelong struggle to achieve democracy and humanity in Burma."

So the petition which Ewen carries demands: "The Prime Minister should officially mark the massacre that ended the peaceful uprising for freedom and democracy in Burma, in 1988, and outline how his government is fulfilling its stated commitment to the democracy process in Burma, by releasing a statement on the 20th anniversary date - the 8th of August, 2008."

Ewen covered 500 miles in 40 days raising over £2,000 for the education of Burmese citizens. He notes that the Burmese government invests a mere 44 pence per head, per year, in education. He now has over 300 signatures on his petition – the vast majority from people who have actively supported him along the road, through the Borders to York, and onwards all the way to London.

Ewen has walked shaven-headed and barefoot in solidarity with the Burmese people ever since their democracy protests in October last year. In winter, in Edinburgh, this was an effective way of drawing attention to the issue – with the pupils at the school where he teaches, and with the wider public.

Throughout, he's been carrying only essential clothing and the five essentials for Internally Displaced People - canvas for shelter, 1kg rice, salt, a knife, and cooking equipment – and no money whatever.

Ewen's hope is "that whatever attention my walk receives, it will allow me to continue raising awareness of the plight of the Burmese people, and in particular the conditions endured by the Internally Displaced People."
