Jo Johnson question Time wire
Jo Johnson was rudely interrupted by his MI5 informants
British Minister of State for Transport Jo Johnson (brother of Foreign Secretary Boris Johnson) appears to have been caught wearing a 'wire' during a recent BBC Question Time interview that discussed the planned attack on Syria.

The voice that 'interrupts' Johnson from a device in his pocket mentions "finding something on Syria" and "it's also been decided that we must tell the media..."

How many other British politicians use a similar device, and does this mean that politicians are merely mouth-pieces and spokespeople for those who really determine government policy?
