Control of one of Britain's biggest government contractors, Interserve, has moved to a new company after administrators were appointed.

It comes after shareholders rejected a rescue deal for the company, which has 45,000 UK staff, and 68,000 globally.

Under a pre-arranged agreement, administrators EY were installed and the assets moved immediately to a group controlled by Interserve's lenders.

Interserve insisted that the deal would protect services and jobs.

The company cleans schools and hospitals, runs catering and probation services, and manages construction projects.

On Friday, shareholders voted 59.38% against a rescue plan to address Interserve's mounting debt pile.

The plan would have seen their stake reduced to just 5%, with lenders being handed the lion's share of the business.

But after the vote, Interserve said that "in the absence of any viable alternative" rescue plan it would formally apply to the High Court to go into administration.

EY was appointed under a so-called pre-pack administration, an insolvency procedure in which a company arranges to move its assets to a another owner before administrators are officially appointed.

It meant that Interserve could avoid a Carillion-style collapse. However, investors have seen the value of their shares wiped out under the financial restructuring.

The lenders who are now in control of Interserve Group include banks RBS and HSBC, and investors Emerald Asset Management and Davidson Kempner Capital.

In a statement, EY administrator Hunter Kelly said: "This transaction secured the jobs of 68,000 employees, the majority of whom work in the UK, as well as ensuring there was no disruption to the vital public services that Interserve provides to the UK Government."

Debbie White, chief executive of Interserve Group, said: "Interserve is fundamentally a strong business and with a competitive financial platform in place we see significant opportunities ahead as a best-in-class partner to the public and private sector."

A spokesman for the Cabinet Office said: "We welcome this announcement. It brings the company the stability required for it to compete for future business and continue to deliver good value public services for the taxpayer."

Interserve accumulated debt after construction project delays and a failed energy-from-waste project in Derby and Glasgow.

Skip Twitter post 2 by @BBCSimonJack ..however. Question is what happens in medium to long term. By tonight lenders will now be owners. No appetite for or expertise in running an outsourcing company. They will want to sell as soon as reasonably possible. Creates uncertainty for customers, staff and suppliers — Simon Jack (@BBCSimonJack) March 15, 2019 Report

Concern for jobs

However, the GMB union said earlier on Friday that Interserve's problems, which come after the failure of Carillion last year, showed it was "time to turn the tide on the disastrous experiment" of outsourcing public services.

Kevin Brandstatter, the union's national officer, said: "Ministers have learnt absolutely nothing from the Carillion fiasco and are hell-bent on outsourcing public sector contracts.

"Shambolic mismanagement is putting jobs put on the line and services in jeopardy. Our public services can't go on like this."

Although Interserve's contracts are expected to continue, there is still concern for jobs in the supply chain.

The National Federation of Builders (NFB) said there would be thousands of workers wondering whether they still have a job, and called for changes in the way the government hands out contracts to big national companies.

Richard Beresford, chief executive of the NFB, said it was time to reform "the procurement process from its foundations to ensure that more regional contractors can compete and win work".

In addition to helping smaller companies, it would "spread risk across fiscally responsible businesses who reinvest profits and are not bound by shareholders," he said.
