Despite being classed as a “low risk event”, organisers of the annual open-air picnic proms have tightened security for Saturday’s concert following recent terrorist atrocities in Manchester and London.

Gates to the Battle Proms in the Queen Elizabeth Oak Field at Hatfield House open at 4.30pm, with the classical music event featuring fireworks, a Spitfire, cannons and cavalry.

The increased security will see a canine search team on site, and random bag checks will be carried out.

Organisers are also advising revellers not to bring domestic knives longer than 5 inches or folding knives with blades longer than 3 inches.

A statement on the Battle Proms website states: “Whilst the Battle Proms concert is considered a low risk event, your wellbeing and safety is paramount to us, especially in light of recent events.

“A canine search team will be working along the queues and within the auditorium.

“When you see the dogs at work please do not distract them, but if you wish to say hello to Patch and Alfie, please ask the handler!”

The website warning continues: “Door supervisors will carry out random and targeted bag searches and customer checks, including searches using pat-downs and metal detection wands.

“Please consider pre-preparing your picnic as far as possible in order to limit the amount of equipment you need to bring with you on the day.

“Knives permitted on site will be limited to domestic knives 5 inches or under, and folding knifes with a 3 inch blade or under.

“Whilst we are keen to maximise visitor safety, we will endeavour to ensure that these measures do not impact on your enjoyment of the day or detract from the celebratory atmosphere that Battle Prommers have enjoyed for the last 20 years.”

Adult tickets for the Hatfield House Battle Proms on Saturday, July 15 cost £38 until midnight the day before the concert.

They cost £43 per adult on the day, either online until 4.30pm or with cash on the gate, subject to availability.
