CALLING all wizards and witches.

Smyths Toy Stores are giving away free Harry Potter Lego this weekend but you might have to get over there quick on your broomstick if you want to nab some.

The 'Back to Hogwarts' giveaway is taking place at all Smyths Toys Superstores throughout the UK on Saturday.

A spokesman added: "We are calling all wizards and witches to celebrate Back to Hogwarts by picking up a free Mini LEGO giveaway from 9am – while stocks last."

The giveaway is only available while stocks last and will be handed out on a first come first served basis with strictly one giveaway per child.

No purchase necessary.
