The Alarm's frontman Mike Peters has been diagnosed with severe pneumonia.

A post on Welsh rock band's social media told fans that the singer/musician has been placed under doctors' orders to focus on the prescribed treatment plan and prepare for a lengthy recovery period.

These means tour dates for Mike and The Alarm will be rescheduled when he is fit.

The page also shared a message from Mike's partner Jules Peters.

She said: "As most of you know, Mike lives with Chronic Lymphocytic Leukaemia and a compromised immune system. Pneumonia has always been one of the biggest threats to Mike’s future health and so now, as a family, we are left with no choice but to batten down the hatches and protect him whilst the medication and treatment help the recovery.

"We have been advised by the Doctors that the recovery period can take approximately 3 months if all goes to plan.

"It goes against Mike’s core as a musician and human being, but for now we are going to have to reschedule all Mike Peters / Alarm engagements scheduled for May / June / July until we know for certain that Mike is back to full health and completely free of pneumonia.

"Unfortunately, this means that The Gathering shows in New York at the Gramercy Theatre on June 17/18 will have to be rescheduled and as soon as we have new dates from promoters Live Nation, we will be in contact with everyone who was planning to attend.

"We totally understand that this is not ideal for those who have already made travel arrangements and pre-booked concert tickets and hotels etc., but hope that we can count on your love and understanding as this situation has come as a complete and unexpected shock for all of us.

"For now we are all focusing on Mike’s health and recovery and will keep you updated on his progress as and when we can. We'd like to thank our medical team for moving quickly and treating Mike with excellent care."

The Alarm formed in Rhyl in 1981 and had a series of hits in the 1980s including Sixty-Eight Guns and Spirit Of ‘76. Following a break-up in 1991, the band re-formed in 2004 and continue to perform.

The band is one of Wales’ biggest ever musical exports, selling over six million albums worldwide and scoring over 15 Top 50 UK Hit singles, while lead singer Mike Peters is respected as a songwriter the world over, and has shared the stage with U2, Bruce Springsteen, Bob Dylan and Neil Young.
