HOME Office staff spent almost £11million on taxis, hotels and flights last year.
The bill - picked up by the taxpayer - has rocketed by almost 50 per cent in only three years.
Taxis alone cost the public £900,000 in 2007/08, up 30-fold from the £30,000 spent in 1997/98.
Meanwhile the bill for overseas hotels reached £4,318,000, a rise of 167 per cent from 2004-05, when the cost was £1,614,000.
It comes at a time when Home Secretary Jacqui Smith is forcing police to take an effective pay increase of only 1.9 per cent.
