Morrissey played a 50th birthday gig in his home city of Manchester last week
Singer Morrissey has cancelled another two gigs, the latest in a string of dates scrapped due to ill health.
Concert organisers said the star's remaining London dates at Brixton Academy scheduled for Friday and Saturday would now not go ahead.
The 50-year-old former Smiths singer had been advised by doctors earlier this week not to sing "to ensure a complete recuperation".
It brings the total number of called off gigs to seven.
Event organisers apologised to fans and advised them to hang on to their tickets for further announcements.
Concerts in Salisbury, Mile End, east London and another date at Brixton have already been called off this week.
Tour organisers are working to reschedule the cancelled dates.
The cancellations come days after the star returned to the stage in Manchester to mark his 50th birthday.
