The eighty-sixth weekly "No shit, Sherlock" award

This week's award was trailed yesterday and goes to 'a wide-ranging economic survey for The Sunday Telegraph' as reported in The Sunday Telegraph:

'The economy will grow by well over a percentage point less next year than the Budget predicted in March.'

"No shit, Sherlock", did anyone really believe Alistair Darling/Gordon Brown's pre-election economic growth predictions?
