Theresa May has called the threat facing the UK 'unmatched', as she announced plans to introduce a new counter-terrorism bill on Wednesday.
Ms May also spoke about the need for internet firms to collect more data on web users, something that doesn't have the support of their Lib Dem coalition partners, she said: "The ability of the authorities to obtain the data they need is declining rapidly. Unfortunately there is no agreement in the coalition or for that matter with the opposition about the need for the Communications Data Bill, and so we're going to have to wait until after the General Election to address fully this increasingly urgent problem".
Middle East analyst and terrorism expert Simon Barrett, who's also a Christian told Premier's News Hour the government will have to balance the rule of law with citizens' freedoms : "We don't want our emails monitored, we don't want our telephone calls monitored, we don't want to become a police state; and so therefore the Government has a very difficult balance of not only protecting us from the threat of terrorisms but the same time shouldn't be using our data against us".
The home secretary's also announced further plans including a crackdown on insurance companies reimbursing people who've paid ransoms to terrorist organisations.
Simon Barrett suggested the measure was obviously necessary in the wake of continued kidnappings of westerners in the Middle East, he said: "Seventy five million pounds has been given to terrorist organisations like ISIS who've caught over fifty aid workers, journalists and others who are working out in the Middle East for [to secure] their release. So it's important that we actually stop funding terrorism organisations in this manner."
Earlier, the Metropolitan Police Assistant Commissioner Mark Rowley warned the terror threat is becoming more diverse.
