Work is continuing to ensure all Glasgow's parking meters are compliant with the new £1 coin.

Glasgow City Council said it was "on track" to have all meters replaced or upgraded before the old coin ceases to be legal tender from midnight on Sunday, October 15.

However, motorists were being encouraged to use alternative methods such as the mobile payment system.

The council said it was focussing on parking meters in areas of "highest demand."

The new 12-sided pound coin, which resembles the old threepenny bit, entered circulation in March and boasts new high-tech security features to thwart counterfeiters.

People have been urged to rummage through their wallets, coat pockets, piggy banks and sofas so that they can spend the old coins, bank them or give them to charity before this date.

Major banks have said that while they encourage customers to allow enough time to hand in the cash, they will continue to accept deposits of round pounds from their customers after October 15.

People may also find they can still hand in the old £1 coins at the Post Office after this date.

The Post Office said customers can continue to deposit their old round pounds into any of their usual high street bank accounts through any post office - even after October 15 - "until further notice".

A spokeswoman for Glasgow City Council said: "We are at an advanced stage of our programme to replace or upgrade parking meters so they can accept the new £1 coin.

"We have focused on ensuring the areas where there is the highest demand for parking have been done first.

"But we are on track to having all meters either replaced or upgraded and able to accept the new coin before the old coin ceases to be legal tender on October 15.

"There are other ways, such as the RINGO mobile payment system, to pay for parking in the city.

"Motorists are finding this cashless method of payment convenient and easy to use."

One pound coins were first launched on April 21 1983 to replace £1 notes.
