Transport for London (TfL) will be forced to reduce services unless it receives a Government grant on Thursday, Sadiq Khan has claimed.

According to reports, any Government bailout would come with conditions, which could affect the multi-billion pound extension to the Bakerloo line.

The Mayor of London said that without financial support, the transport body must cut its Tube and bus networks.

TfL is legally treated like a local authority, which means "we have to be able to balance the books", he told LBC radio.

"We'd have to reduce the bus services we provide, we'd have to reduce the Tube services we provide to save money," he said.

"If we don't get the deal done today, the CFO (chief financial officer) of TfL has legal duties that he has to follow."

Mr Khan continued: "At a time when the Government is wanting us to increase services to get into the recovery phase, we might be required to cut services because the Government is failing to give us the grant support we need."

TfL has been using its cash reserves to meet the £600 million monthly bill of operating services.

It says it needs around £3.2 billion to balance its proposed emergency budget for 2020/21.

A decline in passenger numbers of 95% on the London Underground and 85% on buses due to the coronavirus lockdown has caused a 90% fall in income.

Mr Khan said TfL has been negotiating with the Government for around six weeks.

"I'm unclear about why the Government are waiting until the 11th hour to agree a deal," he said. "It is really bad form."

Bromley Council previously challenged plans to bring tube services to the borough, which would run to Lewisham before taking over the existing Hayes line.

Given many Bromley residents rely on the current Hayes line, the Council is arguing for additional capacity and connectivity for already existing services in the town centre, instead of an extension.
