David Cameron will outline plans to transform the economy in his first major speech as prime minister.

The new leader of the UK has said that the economy was heading in the wrong direction under Labour and that the economy should be rebalanced in favour of manufacturing, business and the private sector.

Cameron has also told critics of a planned rise in capital gains tax (CGT) to wait for the Budget before coming to any conclusion. Some of Cameron's own senior Tory MPs have attacked the planned rise on non-business CGT - which could see taxes on the profits of second home and other asset sales more than double to 40% or 50% - as a tax on the middle classes.

"People don't yet know what our proposals are. Everyone's getting a bit ahead of themselves on this issue. We have to be calm about this because in a coalition there are inevitably going to be arguments and discussions about tax policy and other policies," Mr Cameron told GMTV.

The new collation government has made reducing the record £156bn deficit and getting people back into work as their priority.

"The Prime Minister is absolutely right to lead from the front and focus this government's attention on rebalancing the economy in favour of manufacturing and the private sector," said David Frost, director general of the British Chambers of Commerce.

"For too long the focus has been on consumption, debt, the public sector and financial services. If we have learnt anything from the last few years, it is that businesses up and down the country will be the real source of future job creation and economic growth."
