More than 5,000 armed soldiers could be deployed onto UK streets in the wake of any major terrorist attack, it has been revealed.
The plan would see an unprecedented military response to terrorism if Islamic State or other fanatics struck in Britain.
Details of the plan emerged after a secret document was mistakenly uploaded to a police chiefs’ website.
It came as David Cameron set off on a four-day trade tour of Malaysia and Indonesia, where terrorism is likely to be at the top of the agenda.
The military contingency plan – in minutes from a closed session of the National Police Chiefs Council (NPCC) – has now been taken down.
