Asked about tax avoidance on ITV1's Agenda, Foreign Secretary William Hague said international agreements are needed to tackle the issue.
He said: "This really needs international agreement to really sort out the international company moving its profits from one country to another. You need international rules and George Osborne and the German finance minister are leading the way on this to get those international rules agreed...
"In the meantime, we've got the increased tax avoidance measures and this great thing of public pressure that you can feel whether from the audience tonight or the Public Accounts Committee.
"It will affect the sales of Amazon, Starbucks and whatever so some of them are feeling they have to do something about it anyway and that is a big improvement."
Watch The Agenda on ITV1 at 10.50pm.
