The cost of the new Scottish Parliament building could reach £430m, it has been announced.
The cost of the new parliament has risen from £40m to £401m
Presiding Officer George Reid blamed the latest increase in the estimated cost on delays in building work and the scramble to finish on time.
He hoped this would be the last big rise in the cost before the Holyrood project is finished in the summer.
The estimated cost is now between £425m and £430m, depending on how much is included in the contingency fund.
Mr Reid and the other MSPs on the parliament's management committee were given the latest cost estimates on Tuesday morning.
The Conservatives condemned the latest price rise as a shacking waste of tax payers money.
