Depreciation and finance leasing

Hello I am preparing an income tax report and I'm currently at the adjustment stage. one of my notes states: Depreciation includes £1600 on an item of plant and machinery acquired under a finance lease. The interest charge in the statement of profit or loss is £1780. Depreciation is charged at a rate of 10% per annum on a straight line basis and a full years depreciation is charged in the year of acquisition. Im finding it difficult to find information on a P&M finance lease, am I correct in thinking the 1600 is deducted from the remaining depreciation amount is added back? and do I put 10% of the interest charge in the deductions? thanks for your help
