JO Swinson last night revealed she has been forced to call in cops after a threat was made against one of her children.

The Lib Dem boss, 39, became visibly upset in the Commons as she told Speaker John Bercow she’d reported an incident to police.

The mum-of-two, who became the first MP to take her baby into a chamber debate last year, choked back tears as she said: “Today I reported to the police a threat against my child.”

It came as MPs discussed abuse and threats of violence they’d received throughout the divisive Brexit debate.

Mr Bercow said: “I cannot overstate the frequency by which I have been informed over the last year or so by members on both sides of the House and on both sides of the Brexit argument of the fact and and persistence of threats that they have received.”

And responding to the East Dunbartonshire MP, the Speaker offered to meet members to hear their concerns.

Earlier in the proceedings, Ms Swinson referenced her five year old son as she urged Boris Johnson to apologise for “misleading the Queen” - and said even the youngster knew he was to “say sorry” when he’d done something wrong.

And last September she brought new baby Gabriel into the chamber during a debate on proxy voting.

Paula Sheriff, Labour MP for Dewsbury, hit out at Mr Johnson for branding the so-called Benn Bill - designed to block him from pursuing a No Deal Brexit in Halloween - the “Surrender Act”.

She described his language as “offensive, dangerous and inflammatory”.

Mrs Sheriff later became tearful as she highlighted the 2016 murder of Labour MP Jo Cox, which happened days before the Brexit referendum.

She said: “We stand here under the shield of our departed friend with many of us in this place subject to death threats every single day.

“And let me tell the Prime Minister that they often quote his words: Surrender Act, betrayal, traitor - and I for one am sick of it.

“He should be absolutely ashamed of himself.”

Mr Johnson replied: “I have never heard such humbug in all my life.”
