Zayn Malik has left boyband One Direction saying he wants the chance be “a normal 22-year-old”.

The group said they would continue as a four-piece for their world tour and record another album – their fifth – later this year.

Zayn said: “My life with One Direction has been more than I could ever have imagined. But, after five years, I feel like it is now the right time for me to leave the band. I’d like to apologise to the fans if I’ve let anyone down, but I have to do what feels right in my heart.

“I am leaving because I want to be a normal 22-year-old who is able to relax and have some private time out of the spotlight. I know I have four friends for life in Louis, Liam, Harry and Niall. I know they will continue to be the best band in the world.”

Zayn quit the boyband’s world tour last week after being “signed off with stress” and returned to the UK after he was forced to defend himself online and declare his love for fiancee Perrie Edwards when pictures emerged of him apparently close to another woman.

In a statement, the rest of the group said: “We’re really sad to see Zayn go, but we totally respect his decision and send him all our love for the future.

“The past five years have been beyond amazing – we’ve gone through so much together, so we will always be friends.

“The four of us will now continue. We’re looking forward to recording the new album and seeing all the fans on the next stage of the world tour.”

Simon Cowell, who discovered the boyband on talent show The X Factor, said: “I would like to say thank you to Zayn for everything he has done for One Direction.

“Since I first met Zayn in 2010, I have grown very, very fond – and immensely proud – of him. I have seen him grow in confidence and I am truly sorry to see him leave.

“As for One Direction, fans can rest assured that ‎Niall, Liam, Harry and Louis are hugely excited about the future of the band.”

A spokesman for the band said Zayn was at home with his family and Perrie.
