As the government seeks to play down rifts between Tony Blair and Gordon Brown, further evidence of divisions among senior ministers has come to light.

In a leaked letter, David Blunkett criticised the Treasury's plans for child trust funds for children from poorer families.

The home secretary said his "major disappointment in the scheme is the low level of investment which is currently proposed and, therefore, the low level of final asset which will be accrued".

His comments came as Alastair Campbell described claims of a deteriorating relationship between the prime minister and his chancellor as "completely overblown".

The former Number 10 director of communications told the BBC that the two men had forged "one of the most formidable political partnerships in British political history".

Today's Independent carries a quote from a "Blair aide" describing the dinner held last week between the prime minister and chancellor.

"He made clear he was prepared to embrace any reasonable point of view held by Gordon, but if they disagreed, Gordon would have to accept that he was prime minister. His message was that you can't have two prime ministers."

Meanwhile, the Times reports that Labour MEPs have been angered by the chancellor's attacks on the planned European Union constitution.
