PM Stresses Importance Of Joint Working By Police Across UK To Fight Terror
The Prime Minister has met with officers from Police Scotland to discuss counter terrorism in the wake of the Westminster attack.
Theresa May stressed the importance of joint working by police forces across the UK during a visit to Govan in Glasgow.
Police Scotland is due to lead on a counter terrorism operation later this year, and Mrs May told officers: "Obviously our thoughts are still with the family and friends of those who were killed in the attack that took place in London last week.
"Of course as we look to dealing with terrorism we need a multi-faceted approach.
"Police Scotland is the second biggest force in the UK, with huge capabilities and capacity, and working with other police forces across the UK to help to keep us safe.
"Thank-you for all that you and your officers do to help keep us safe and secure.
"Obviously as we look to the future we want to make sure, ensure that we are getting that cross-fertilisation across police forces.''
On the counter terrorism operation later this year, Mrs May said: "It is an important example in showing how forces can work together in this very important area, because it is essential that we use all our capacity but also that we have that cross-fertilisation and experience and expertise between forces.''
