My Lords, I thank the noble Lord, Lord Davies, in his absence for this amendment and thank the noble Lord, Lord Tunnicliffe, for moving it and speaking to it. The Office for Budget Responsibility’s remit is clearly defined in legislation, under the Budget Responsibility and National Audit Act 2011, as being,
“to examine and report on the sustainability of the public finances”.
In doing so, the OBR must produce at least two forecasts per financial year, which must include the impact of government policy where it can be quantified with reasonable accuracy.
The Government expect the OBR to include the impact of the withdrawal agreement alongside its forecast of the UK’s economic and fiscal outlook as soon as sufficient information is available. That would contribute to the transparency which the noble Baroness, Lady Kramer, is looking for. But the Government cannot dictate when that might be. This is the important distinction. It is therefore not appropriate to request the OBR to produce analysis specifically for a legislative debate, as this will draw the OBR into political debate, which could undermine its reputation as an independent and objective institution.
