Speaker John Bercow lost his temper with Suffolk Coastal MP Therese Coffey and health secretary Jeremy Hunt today for using their mobile phones on the front bench.

The chairman of House of Commons debates told the pair that they were 'impairing decorum' and they were being 'rank discourteous' to the shadow secretary of state for health Heidi Alexander.

When Dr Coffey, the deputy leader of the House of Commons, continued to use her mobile phone he interrupted proceedings again to admonish her.

He told her to put the device away or to get out, adding that it was 'discourteous to behave like that'.

While not commenting directly on the lecture from Mr Bercow, she later tweeted that she had planned to tweet: '@heidi_mp opening interesting debate on NHS bursaries. Classic eg of agreeing outcome (more nurses), different solutions (& Lab no extra £)'
