London could become a no-go, danger zone, before the G20 summit — staging of which will cost around £19 million.
Apart from reports of plans of anti-globalistation protests, intelligence officials have warned of “severe” terrorist threat against Britain.
The authorities have already initiated arrangements to “seal” hotels where leaders would be staying fearing Mumbai-style terror attack. However, the government has denied such a possibility but said an alert was in place.
Security arrangements are likely to cost a million pounds. Sources said a close watch is being kept for any increase in smuggling of small arms through ports and airports. Apart from increased security around the locations, the leaders would be provided with extra police officers.
Thousands of uniformed officers will also be on the streets to prevent legitimate protests from being hijacked by violent activists. It is learnt that anarchist groups and environmental activists are joining hands for a number of demonstrations, which are being advertised with slogans such as “Storm the Banks” and “Bash a Banker”.
