Ed Zander could come under renewed pressure to step down as chief executive of Motorola today as new figures showed the handset maker lost more than seven percentage points of market share in the second quarter.

Motorola narrowly maintained its position as the second-largest handset manufacturer but its share of global sales fell to 14.6 per cent, from 21.9 per cent a year ago, according to figures released today from Gartner, the research company.
