The UK’s prime minister Theresa May has finally conceded to the march of time and today upgraded from a BlackBerry to an iPhone.

The prime minister – whose Maidenhead constituency is home to Blackberry’s European headquarters – had resisted upgrading to the iPhone, even after they were phased in for the rest of her Downing Street team.

Once cutting edge for allowing users to check their emails on the fly, Blackberries have long since lost their corner of the smartphone market to Android models and the iPhone.

May will also not be allowed to install her colleague Matt Hancock’s eponymous app, which has suffered data leaks.

This might be a relief to May, who joked about it at this year’s Downing Street correspondents dinner.

May is not the only powerful female politician reluctant to give up her Blackberry.

US Democrat presidential hopeful Hillary Clinton was reportedly wedded to her Blackberry Curve, getting her staffers to buy the model off Amazon or eBay even after Blackberry stopped making them.

Clinton’s insistence on using her Blackberry in 2016 was partly responsible for the investigation into her use of official and non-official email addresses.
