FOREIGN Minister and Bournemouth MP Tobias Ellwood has declared that 'we must not let the terrorists win' following the news that 15 Britons are among the 39 people killed in the Tunisian beach massacre.

Mr Ellwood, who is MP for Bournemouth East, confirmed the figure yesterday and described the Sousse atrocity was 'the most significant terrorist attack on the British people' since July 7, 2005, when 52 people were killed.

Kalashnikov-wielding student Seifeddine Rezgui targeted Western tourists as he terrorised the popular resort.

Speaking to the Daily Echo this morning, Mr Ellwood said that an additional COBRA meeting was chaired today by the Home Secretary, Theresa May.

Plans are now in place to send extra medical and police resources and to upgrade security for residents, visitors and holidaymakers in the area.

He added that the meeting was held "to ensure we have the full consular support for all those caught up in the horrific atrocity".

Asked whether people should change their travel plans if they have booked a holiday abroad in the near future, he said: "We must be vigilant and aware but we must be united in condemning the atrocity and not let the terrorists win.

"The more we stay at home and don't travel abroad, the more the terrorists have won."

One of those killed is reported to be 24-year-old fashion blogger Carly Lovett from Gainsborough, Lincolnshire.

Another British victim was named as Adrian Evans, who worked for Sandwell Council in the West Midlands as a manager in the gas services department.

Speaking in the Foreign Office on Saturday, Mr Ellwood said: ''Sadly, I can confirm that at least 15 British nationals were killed in yesterday's atrocity, but I should stress that the number may well rise as several more have been seriously injured in this horrific attack.''

He added: ''This is the most significant terrorist attack on British people since 7/7 and highlights the ongoing threat of Isil.''
