Asked whether David Cameron would back calls for a consumer boycott of firms which avoid tax, the Prime Minister's official spokesman told a regular Westminster media briefing:
The issue for Government is how we tackle that tax avoidance, and the Treasury have been setting out what we intend to do today.
What we have to do in Government is make sure we are tackling that kind of aggressive tax avoidance. We are doing that in a number of ways. We are bringing in a general anti-avoidance rule, we are working with other countries.
The question of a boycott was "an issue for individuals", the spokesman said.
Clearly, we think that all companies should make a fair contribution to taxes and clearly that's a view that is shared by taxpayers and consumers.
