Gwent

Two other defendants, Ashton Evans, 20, from Newport, Gwent, and Dmirjus Paulauskas, 23, from Croydon, are each charged with two counts of failing to disclose information about terrorist acts, which they deny.

Blaenau Gwent, Merthyr Tydfil and Neath Port Talbot were the worst affected areas per head of population.

Gwent Police said it was made aware of the video on Wednesday evening, which showed a Lliswerry High School pupil being assaulted by a group of children as he was held by a man.

Gwent Police also confirmed officers were aware of a separate allegation of assault involving a different child from earlier in the day and that investigation was also ongoing.

The Principality said much of the market strength to date is currently "centred" in south Wales, with Bridgend, Blaenau Gwent and Caerphilly reaching "fresh record prices" between January and March this year.
