Mortimer, part of popular British comedy duo Vic and Bob, was due to go on a national trek with his partner Vic Reeves in November (15), but the first leg of their 25th anniversary tour was cancelled so he could recover from the operation.

The comedian has now been given the go-ahead from medics to perform, and the second leg of the tour kicks off in Leeds, England on 30 January (16).

Mortimer wrote on Twitter.com, "Tour update... Doctors just passed me fit to do second leg of tour next (sic) month."

The 25 Years of Reeves and Mortimer: The Poignant Moments tour concludes in London on 16 February (16).
