Interview exit strategies (3): Diane Abbott's mobile phone comes to the rescue

Today I have to thank Diane Abbott MP for adding to my small collection of politicians walking out of an interview (for others, see below).

This is the first one in which the interviewee's mobile phone came to the rescue at a particularly awkward point in the questioning - silent though the ring seems to have been.

Could it, I wonder, be a neat ploy that becomes a precedent for many more such 'escapes' in the future?

Classic interview exits:

• 'Here today, gone tomorrow' politician walks out of interview with Robin Day
• Mandelson walks out rather than answer a question about Gordon Brown
