In a race for limited resources, it is the energy efficient that will win the race

It does not seem to me that the steps which would be needed to make Britain - and others - more comfortable in their relationship in the European Union are inherently so outlandish or unreasonable.

We believe in a flexible union of free member states who share treaties and institutions and pursue together the ideal of co-operation. To represent and promote the values of European civilisation in the world. To advance our shared interests by using our collective power to open markets. And to build a strong economic base across the whole of Europe.

Christmas gives us the opportunity to pause and reflect on the important things around us - a time when we can look back on the year that has passed and prepare for the year ahead.

Easter is all about remembering the importance of change, responsibility, and doing the right thing for the good of our children.

Taken as a whole, Europe's share of world output is projected to fall by almost a third in the next two decades. This is the competitiveness challenge - and much of our weakness in meeting it is self-inflicted. Complex rules restricting our labour markets are not some naturally occurring phenomenon.

It is vital that we get these policies right as we take forward our plans to drive down the deficit and transform our economy.
