Visitor numbers rose 29 per cent to more than one million in 2013 but pegged Government funding has led to Deverell lookimg to make cuts.
He says Kew faces a £5m shortfall in 2014/15 but will fill a third of that through more self-generated income in the next financial year.
Deverell said; "costs will be reduced and these will include changes in staffing". Deverell will ask for voluntary redundancies, reduced working hours, unpaid leave and compulsory redundancies.
Some 125 of Kew's 750 staff could go. Back office staff, and scientific personnel could be first hit.
