UK PM David Cameron prepares for Europe speech

On Wednesday UK Prime Minister David Cameron will make his long awaited speech on the UK's relationship with Europe and how it might change.

The speech was postponed on Friday because of the hostage crisis in Algeria.

Some business leaders are warning of the dangers of growing uncertainty over the UK's position in Europe.

Others believe that a looser relationship with the EU would bring benefits.

The BBC's business editor Robert Peston reports.
