In 1885 he was again elected to Parliament, this time as MP for Marylebone East, and re-elected at the 1886 general election.
 Beresford constantly pushed for greater expenditure on the navy, resigning his seat in protest on this issue in 1888.
Meanwhile, in 1886 he had also become Junior Naval Lord.
The Naval Defence Act 1889, which increased naval spending, was passed partly as a result of public pressure resulting from this action.

Beresford was a believer in promoting physical recreation beyond the services, being one of the founding committee of the National Physical Recreation Society which began in 1886 under the presidency of Herbert Gladstone.
In 1888 he put down a motion in Parliament proposing that the County Councils (formed in 1889) provide a gymnasium for every 100,000 inhabitants.
William Penny Brookes invited him to be president of the Wenlock Olympian Society Annual Games in Shropshire for the years 1888 and 1889 but he was unable to be present at the sports, because of other commitments.
In the latter year news of his affair with the Countess of Warwick broke after she threatened Lady Charles Beresford; despite this Brookes, an advocate of physical education, and Beresford had a warm correspondence from 1888 until Brookes' death in 1895, and Beresford was elected an honorary member of the Wenlock Olympian Society in 1891.

From 1889 until 1893 he was the captain of HMS Undaunted, which was part of the Mediterranean Fleet.

In 1898 Beresford was promoted to rear-admiral and again entered Parliament, this time representing York, though he spent much of his time in China representing the Associated Chambers of Commerce.
He spent 100 days in China, and on his return to London, spent 31 days writing The Break-Up of China (1899).
He resigned from parliament in January 1900 to become second in command of the Mediterranean Fleet, and left London to take up this position the following month.
A dislike steadily developed between Beresford and Jacky Fisher who was then commanding that fleet.
 Shortly after his arrival, Beresford took a company of men ashore and used them as stand-ins for ships to practice manoeuvring and assembling a fleet.
Fisher noticed the display and publicly sent a signal demanding to know why Beresford had landed his men without permission.
Lord Charles resented his superior as a social climber from unknown origins, while Fisher was jealous of Beresford's inherited wealth and social position.
In early February 1902 he left his position in the Mediterranean Fleet and returned to England.
