By any standards it has been a busy week for me in Parliament. I'm chairman of the trade and industry committee and we published a report on Monday that called for government action to save our sub post office network.

Post office branches will lose income as a result of the ending of the post office card account (POCA). This meant the committee was very worried about the future of the post office network and the effect post office branch closures would have on their wider communities. We said: "If the Government fails to act, the network and all the benefits it provides for communities could be lost forever. If the country wants a comprehensive network of post offices to continue, a more explicit funding mechanism must be put in place, together with product diversification and a replacement for the post office card account."

Most of the Government's partners in the POCA assumed it would continue in some form after 2010. This has led to a sense of betrayal among sub-postmasters.

Tuesday saw a passionate debate about the need for an inquiry into the conduct of the Government in the period leading up to military action in Iraq.

I was very disappointed that the Government refused to commit itself to such an inquiry.

Their excuse - that it would undermine our troops in Iraq - was just ridiculous.

Meanwhile, I did a bit of research after Mike Foster's bizarre attack on Conservative tax plans in his column last week. The truth is that we are not committed to any tax cuts. Even if we did introduce, over the five years of a parliament, the £21bn reduction put forward in the independent report he seized upon, what would it mean?

Well, over the last five years, Gordon Brown has increased taxes by more than four times that sum - well over £90bn. No wonder we are all beginning to feel overtaxed by Gordon! Hard-working families in Worcestershire just can't afford more taxes.

We Conservatives won't be writing our first budget until after we have won the election - and we won't promise tax cuts that would undermine our economic stability. But Mike Foster ought to have the honesty to admit that even if we did cut taxes over five years by only a quarter of what his government has increased them by, it wouldn't mean a return to the Dark Ages! Come on Mike, treat us like grown-ups, please.
