But she warned that everyone must continue to be vigilant with less than 40 days to the millennium.
In her response to a written Parliamentary Question, Mrs Beckett said: 'I am delighted to report that work on business critical systems is now complete in all Government Departments and Agencies with one exception. This means that systems have been fixed, tested and successfully put back into operation.'
'The MoD has completed over 99% of work on its critical systems. Although there has been a small slippage within part of the MoD's complex programme, this has been offset by progress elsewhere, and its critical systems are now predicted to be completed by the end of November.
'In any event robust and tested contingency plans are in place to maintain defence capability.'
'Business Continuity Plans (BCPs) and Millennium Operating Regimes (MORs) are essential safeguards against the impact of unforeseen bug failures and the other particular pressures of the Millennium holiday period. I am pleased to say that all Departments and Agencies now have robust and tested BCPs and MORs in place.'
Mrs Beckett added: 'I reported, in my last statement, that as part of the Central Government MOR, Government and the key infrastructure providers would be testing proposed information flows. "Exercise Herald" took place on 26 October and showed that the structures being put in place are sound.'
Turning to the wider public sector, Mrs Beckett reported that all sectors of the UK's national infrastructure - including local authorities, utilities, police, fire, telecommunications and healthcare - have achieved 100% 'blue' status under the Action 2000 infrastructure programme. This means that independent assessors have not identified any risk of material disruption as a result of the Bug, and that customers can expect a normal service over the Millennium.
Mrs Beckett emphasised: 'Although almost all testing across government and the national infrastructure is now complete, the possibility of failures, however low, still remains. With less than 40 days to the Millennium, we cannot rest on our laurels.'
' To address any remaining or unforeseen risks, we are asking all providers of key services - including government departments - to keep their business continuity plans under review so they can continue to deliver essential services come what may.'
