Saturday's continuing sunny weather has added to the pressure on Britain's motorways on the Jubilee weekend.

Sun-seekers heading to southern coastal regions joined traffic bound for central London for the Jubilee celebrations.

The BBC travel unit said traffic had been fairly constant since around 0730BST on Saturday.

However, Friday's huge tailbacks on the M25 London gyratory had eased, with delays of five or 10 minutes reported.

Jubilee visitors advised to stick to public transport

Particular problems were reported on the M1 in west Yorkshire, where an accident involving two caravans has left two lanes closed northbound.

Train services were largely running smoothly, but there are some problems.

The Gatwick Express from Victoria is now running a reduced service with trains leaving every half hour.

And Chiltern Railways had replaced some services with bus links due to maintenance work.

An AA spokeswoman said traffic around London was "heavy but flowing".

However, travellers are still advised to consider taking public transport into the capital.

Sun factor

Road closures ahead of and during Jubilee events are expected to make parking even more difficult.

South-east England train companies are adding extra carriages to trains to take people into and out of London for Jubilee events.

Adapted Saturday services will run on both Bank Holiday days.

Traffic conditions are likely to remain "about the same" over the rest of the Jubilee holiday, said the AA.

Fairly fine weather will keep traffic heavy, though traffic bound for southern resorts is likely to ease locally as coastal weather becomes more patchy.

Earlier the Highways Agency said it was suspending routine maintenance on major roads while trying to keep as many lanes open as possible.

The AA has sent out 100 extra patrol staff over the weekend to cope with the increased traffic, with the West Country a particular concern.

The RAC says it will also have extra patrols for busy periods.

The AA spokesman said Tuesday would see another build-up of traffic as holidaymakers returned home.

But school half-term holidays might help reduce the congestion, with families extending the break.

The Maritime and Coastguard Agency said huge crowds were expected at seaside resorts over the weekend and warned tourists of the dangers of drinking and swimming, tides and slippery cliff edges.
