This week, literally hundreds of you have written to me about supporting a Financial Transaction Tax, otherwise known as a Robin Hood Tax.

Many opponents of such a tax argue that the cost will simply be passed on to consumers, but this can be avoided by focusing on a distinct area of bank operations - the high-frequency large-volume trading of financial institutions in the ‘casino economy'.

I have asked the Prime Minister to put pressure on other nations to adopt a Robin Hood Tax when the G20 meets this week and have also argued that the UK could also go it alone immediately with, for example, a currency transaction levy.

It's great to get so much support from constituents on this issue, which has been a priority for me since first being elected, and I will be taking every opportunity to raise it in Parliament.
