The budget for new helos across the board (Merlin CSP, SABR, BLUH, SCMR, SAR) was about £4.1Bn.
It is now (according to the white paper) "over £3Bn" (actually only just over £3Bn).
This tallies REALLY well with the well publicised SH shortfall, not to mention some of the other points highlighted in the recent NAO Battlefield Helicopters report.
