The Edinburgh East MP said: "Edinburgh University is located in my constituency and it was great to see so many students had made the effort to travel down for the march.
"Even though these proposals don't cover Scotland, they will have an enormous effect on higher education in our country.
"I'm concerned that young people in England will increasingly want to study in Scotland. This could squeeze out otherwise bright and able Scottish students. I'm also worried that the sky-high costs will put off Scottish students from studying in England."
