Anneliese welcomes news from the Commission of a "tax transparency package" and challenges the Tories to give the proposals their support.
Ever since last year's Lux Leaks revelations, Anneliese and her fellow Labour MEPs have been putting pressure on the Commission, and its President Jean-Claude Juncker, to take more action to crack down on aggressive tax avoidance.
Following that campaign, today's announcement means that countries now must automatically inform one another of sweetheart tax deals with multinational companies when there is a cross-border impact, and can no longer hide behind "commercial confidentiality" excuses.
"This just goes to show that all the pressure Labour MEPs have been putting on the Commission has paid off," said Anneliese. "The message today is clear: countries should not be organising sweetheart tax deals with big companies, in secret, in ways that can be hugely damaging to other countries.
"But much more action is needed for us to stamp out aggressive tax avoidance once and for all - like agreeing a common definition of tax havens, and blacklisting firms that evade tax and the advisers that help them to do it. Those are the kind of measures I am going to be pushing for as I draft the European Parliament's proposals for further action on tax evasion and avoidance.
"These are proposals that everyone should get behind. As we prepare for the Budget later on today in the UK, I want to hear the Tories say that they are committed to ending these tax practices once and for all too. If they don't, we'll know whose side they're really on."
