Good morning, here are the major traffic and travel details you need to know if setting out this morning.

One lane closed on M1 southbound between j2 and j1 because of a broken down vehicle - traffic is slow. Also busy at j1 for Staples Corner with queues continuing onto the A406 towards Wembley.

Speaking off the A406, an incident eastbound is causing tailbacks through Edmonton - also affecting Waltham Way towards the A406. And westbound very slow from Silver Street all the way around to New Southgate where the traffic eventually clears.

Busy on A1 southbound approaching Stirling Corner, Borehamwood, and Mill Hill Circus.

Queues anticlockwise on the M25 from Watford round to the M4.

Slow traffic into Watford in Eastbury Road.

Slow on local roads at junction 26 of the M25 near Waltham Abbey.

On the tube, severe delays on the Northern line. There is no service between Camden Town and Morden via Bank and between Charing Cross and Morden due to a signal failure at Kennington. Severe delays on the rest of the line. Tickets are being accepted on local buses, London Trams, South Western Railway and Thameslink. TfL asks for passengers to avoid the Northern line and use other routes if possible.

Good service on all other lines.

Weather-wise, a mainly cloudy day with some outbreaks of sunshine, particularly this morning. Temperatures of around 21 or 22 degrees celcius.
