BBC News => BBC denies Doctor ‘quits’ report
Isn’t this how it started when Eccleston quit, too? The Doctor hasn’t got that many regenerations left…

The Sun claimed the actor, 35, planned to depart next year, in the middle of the fourth series of the hit programme.

But he was currently filming the third series, a BBC spokeswoman said, adding that any episodes beyond that had yet to receive the go-ahead.

“When a further series is commissioned, we will be able to confirm his involvement,” she said.
