Senior Partner

Alastair is the head of the firm’s parliamentary and planning teams and a Parliamentary Agent, one of a very small number of lawyers entitled to promote and oppose private and hybrid legislation in Parliament. He acts for clients in the public and private sector in promoting and opposing Parliamentary Bills, development consent orders, harbour orders, transport and works orders, byelaws and other secondary legislation.

His work includes the promotion of and opposition to major infrastructure projects, which in turn requires specialist knowledge of planning law, compulsory purchaseenvironmental and highways law and practice. He also promotes legislation for public bodies who require additional statutory powers, requiring knowledge expertise in all aspects of public law and regulatory work.

Alastair qualified at Sharpe Pritchard and has practised in the Parliamentary and Planning team since then. He has promoted more Bills in Parliament than any other agent in that time and has acted on most of the major infrastructure projects that have attracted parliamentary scrutiny.

Alastair advises clients in a wide range of sectors including central government, local government, real estateregeneration and transportation.

Alastair has been ranked in the top tier of the parliamentary section in Chambers UK and the Legal 500 for a number of years.

Membership of relevant organisations: Alastair is a former honorary secretary and president of the Society of Parliamentary Agents and is a member of the Compulsory Purchase Association.
