Mr. Burstow: To ask the Secretary of State for Health what progress has been made in meeting the public service agreement target to increase in each year the proportion of drug users successfully sustaining or completing treatment programmes. 
Caroline Flint: The most recent estimate of the number of workplace deaths caused by second-hand smoke was published in the British Medical Journal on 2 March 2005 in a report by Professor Konrad Jamrozik. This gave an estimate of 617 deaths a year in the United Kingdom. The author acknowledges that the results are distinctly sensitive" to some of the underlying assumptions. A copy of the paper is available in the Library.
A partial impact regulatory assessment (RIA) has been published alongside the Choosing Health White Paper, which gives initial estimates of the possible impact on smoking prevalence. This estimates that the proposal outlined in the White Paper might reduce smoking rates by between 0.7 and 1.7 percentage points. The RIA contains estimates of costs and benefits of a ban on smoking in the workplace. A copy is available in the Library.
Mr. Hancock: To ask the Secretary of State for Health if she will list those sites in England and Wales, within her responsibility, which have been identified as surplus to requirements; what plans have been identified as theirpossible future use; what consultative process will be followed in each case; and if she will make a statement. 
The list includes 22 sites that are due to transfer to English Partnerships (EP) as part of a wider agreement with the Office of the Deputy Prime Minister and in support of the Government's sustainable communities plan. 67 surplus NHS sites have already been transferred to EP this year, as part of the same programme. It will be for EP to decide how to take forward all these sites subject to the normal planning process.
The list also includes other larger sites which are surplus to the requirements of the NHS but which are not being transferred to EP. Arrangements for the disposal of these sites are at various stages and it is not clear in every case exactly what the future use will be. It is likely that most will be redeveloped for residential purposes; the manner of development will be the subject of local consultation and the planning process.
Ms Harman: In relation to postal voting we have no plans to change the provisions of the Representation of the People Act 2000 which requires the Secretary of State to consider any application to pilot all postal voting.
24. Mr. Andrew Turner: To ask the Minister of State, Department for Constitutional Affairs what (a) the earliest and (b) the latest date was on which returning officers were able to dispatch postal votes to voters during the recent general election. 
Ms Harman: In the general election last month, the earliest date on which postal votes could be dispatched to voters was 19 April. They cannot be printed or dispatched until close of nominations and the latest date they could be dispatched was 4 Mayfor replacements where the original had gone astray.
Ms Harman: We want to ensure that we have electoral registers which are comprehensive and secure. We are proposing that to be included on the register an individual should give a signature and date of birth. We currently propose to stick with one form per household.
Ms Harman: The number of UK registered electors at the general election was 44,261,545. This figure excludes the registered electors of the Staffordshire South constituency who numbered 69,604 as at 26 May 2005.
