Louise Lear, 48, who presents for the BBC couldn’t control her laughter as her colleague, news reader Simon McCoy, 54, handed over to her, The Sun reports.

The hilarious footage of the broadcast shows Lear struggling to keep a straight face as she begins to cry with laughter.

“You alright?” McCoy asks her before the pair attempt to redo the handover — but she just can’t stop.

Lear tells the camera: “I’ll try and keep it together because it’s not a laughing matter with the weather in Scotland today,” as she begins to wipe away the tears of laughter from her eyes.

However, every time she seems to have composed herself, another bout overcomes her and she takes to turning away from the camera in an attempt at hiding her ill-timed fit.

But it was the “gale force gusts into Wales” which particularly set her off and her voice becomes high-pitched and garbled.

She then pushes her hand to her mouth in an attempt to stem a further outburst and apologises to the audience.

But it wasn’t to last.

The “low pressure in the north-west” set her over the edge and Lear goes back to giggling, tears now visible around her eyes.

Thankfully, it seems that after this final fit, poor Lear was able to control herself and the clip ends as she appears to recover her professional manner.

Many Twitter users have speculated on social media as to what could have set her off, with some venturing that perhaps McCoy had said or done something prior to the broadcast to cause the giggle fit.

We’ve all been there, Lear …
